Gemma Monk was seconds away from the happiest moment of her life when her world turned black. As the 35-year-old prepared to walk down the aisle at Oakwood House in Maidstone, she heard her name called. 

When she turned, a thick drench of black paint hit her. The substance splattered her £1,800 white gown, her face, and her eyes in front of horrified wedding guests. 

The attacker was Antonia Eastwood, the wife of Gemma’s older brother, Ashley. Eastwood fled the Victorian mansion immediately, leaving her victim standing in the hallway in a ruined dress. 

Despite the ‘spiteful’ assault, the mother-of-two refused to let the sabotage win. She retreated to a changing cubicle to scrub the paint from her skin. 

An usher was dispatched to find a replacement dress. Although the borrowed gown was too large, Gemma was determined to proceed with the ceremony.

**PERMISSION TO USE ON THE BASIS COMMENTS SECTION IS TURNED OFF ON THE ARTICLE** WORDS BYLINE: Julia Roberts ADDITIONAL REPORTING BY NICOLA JORDAN Why did my sister-in-law do this to me on what was supposed to be the happiest day of my life? It???s the question that haunts Gemma Monk after her dream wedding gown was daubed with black paint?? -seconds before she was due to wed her childhood sweetheart. The mum-of-two was subjected to the spiteful??? revenge??? attack witnessed by horrified wedding guests invited to see Gemma and Ken Monk tie the knot at Oakwood House Register Office in Maidstone. Antonia Eastwood, who is married to Gemma???s older brother, Ashley, fled the venue, leaving her splattered victim in tears. Remarkably, Gemma, 35, pulled herself together, scrubbed her face and body in a changing cubicle and borrowed a dress fetched by an usher to marry her partner of more than 20 years. She told KentOnline: ???We had waited for that day for so long. Nothing was going to stop me. ???She was determined that the wedding was not going to happen ???I did not think twice, I would have walked down the aisle in my knickers and with black paint over my face if I had to.??? Gemma was speaking on Wednesday after Eastwood, 49, who now lives in Manchester, was sentenced at Maidstone Crown Court for two offences of criminal damage. The court was told that the bill for repairs and "loss of revenue" at Oakwood House was believed to exceed ??5,000. Neither Eastwood nor her husband were invited to the nuptials following an ongoing feud which flared up after their wedding, which was a year before the Monks were married. Gemma said that she had been wrongly accused of ???trying to trip up??? Eastwood during her wedding to Ashley in Dover in September 2023. The relationship between the two couples has since soured despite Ken once being Ashley???s best friend, who introduced him to??Gemma when she was 14. The Monk???s ceremony went ahead on May 24, 2024,?? two hours after the paint attack at the Victorian mansion, which was forced to close while repairs were carried out. Since then, Gemma, a mental health care worker, has suffered depression and been unable to work. She choked back tears as she read her victim impact statement to the court. She said: ???To have paint thrown over me by my brother???s wife changed my outlook on life and made me question whether I had done something really bad, whether I had done something wrong. ???This has had a dramatic impact on my life. Even while I was providing this statement at the police station, I got extremely emotional and started crying while talking about the incident. ???Since the incident, if it wasn???t for my children or my family, I don???t think I would even get out of bed to care for myself. ???I have lost all my dignity and good habits in life. I have lost who I used to be. ???This has turned the most special day of my life into the worst memory I will never forget, and neither will my family.??? The ordeal also came at a time when Gemma had had a cancer scare, during which she lost weight, going down to a size four. Gemma, who has since been given the all-clear,??said her sister-in-law knew about the medical issue at the time?? but ???still decided to ruin the most important day of my life and put me at risk.??? The couple also called off plans to go?? on their dream honeymoon to the Maldives because she ???wasn???t up to it.??? Recalling that fateful day, she said: ???I had a gut feeling, a bad feeling that something was wrong when I got out of the car with my dad. ???But he said it must be nerves.??? As she stepped into the cream-walled carpeted hallway with father Jason, bridesmaids and flower girls, she heard her name called out and thought somebody had accidentally trodden on her dress. In a split second, out of the corner of her eye, she saw someone throw black paint at her. Prosecutor Pietro Matarazzo told the court on Tuesday: ???Her wedding dress turned black. It was splattered with paint, as were her eyes, face, and skin.??? Gemma, realising it was her sister-in-law who was with her brother, grabbed her by the hair, but she got away. Police were alerted, leading to a voluntary interview three months later in which she replied ???no comment??? to all questions. However, after pleading guilty to the offences, she later admitted to the author of a pre-sentence report prepared by the probation service that the incident was a revenge attack. The ???paint???, which was never forensically tested, was at times referred to as dye by the prosecutor. But, whatever the substance, the court heard professional cleaning by specialists failed to remove the stains, dashing Gemma???s wish to hand it down to her daughter. Gemma??and Ken, 39 who live with their son Tyler, 18, and daughter Naomi, 11, in Herne Bay, had been saving for years for their big day She said: ???It had to be 100 per cent right. I chose Oakwood House because that was where my birth was registered.??? The wedding for about 50 guests and included a reception at The Fields at Aylesford, cost about ??8,000. Gemma splashed out ??1,800 on her dress, which she fell instantly in love with, in contrast to the replacement gown, which was too big for her. Clement Idowu, defending, said Eastwood had written a letter to the court and wanted to reiterate through him "her wish to apologise" to her victim. He also spoke of her depression, stating that the legal proceedings had "taken a toll" on her mental well-being and that she was "very fearful at the prospect of going to prison". No details explaining why she acted in revenge were revealed during the hearing. Before passing sentence, Judge Oliver Saxby KC acknowledged that while "emotions were high" and those involved would "never forget," they should now move forward in their lives. He also told the court that he was following sentencing guidelines and "not being kind or bending over backwards" by sparing the defendant an immediate spell behind bars. But, imposing a 10-month jail term suspended for 12 months with 160 hours of unpaid work, he poured scorn on Eastwood's actions and her attitude towards them. "This was meant to be a special day for Gemma Monk and her family. Courtesy of your conduct, it turned into a nightmare," he told her. "It is not so much that what you did was upsetting and frightening in the moment, and it was both of those. "It was also that you, by what you did, deprived her and her family - the wedding party - of the occasion they deserved and the memories that anyone who gets married cherishes. "Worse than that, there is a lingering suspicion that even if you do trigger regret now, it's been a while coming, that deep-down for some time you thought she deserved it. "All this stuff about it being on the spur of the moment - yeah, right. You got it into your head that you wanted to wreck her day. "And you did, and it was horrid and nasty and mean." Explaining why he could suspend the prison sentence in light of mitigating factors that included her previous good character, realistic prospect of rehabilitation, the delay in proceedings and prison overcrowding, Judge Saxby added: "You richly deserve to be punished for what you did, but I must keep what you did in proportion and keep it in context. "Emotions are high in this court, but I must keep my feet on the ground and apply the guideline which helps me to decide whether to send someone to prison." Eastwood was also handed a 10-year restraining order and told to pay ??5,000 compensation - a total of ??4,000 to her sister-in-law and ??1,000 to Oakwood House - at a rate of ??100 a month. Although he described the amount to be paid to the venue as "a drop in the ocean" of the costs incurred, Judge Saxby stated it was "necessary to compensate Ms Monk for the misery caused". In court, Gemma said she maintained eye contact with Eastwood, who sat shaking in the dock throughout the proceedings. Reacting to the sentence, Gemma said: ???I will never accept her apology. I thought the sentence was too light. She should have got at least 23 months for the wait we have had to get this to court.??? But Gemma said the outcome has given her some closure, and she now knows it???s time to get on with her life. She told KentOnline: ???I want to find myself again. I want to move on. ???On that day, I managed to smile for the camera because I was marrying the man I love. ???But we don???t celebrate our anniversaries because of what happened. We plan to take our vows again and on the same date. ???That way, it may override the memory, and we???ll be able to celebrate. ???And maybe we???ll go on that honeymoon.???

‘I did not think twice. I would have walked down the aisle in my knickers with black paint over my face if I had to.’ 

The couple had saved for years for the £8,000 ceremony. Gemma chose the venue because it was where her own birth had been registered. 

The motive for the attack appears to stem from a toxic family feud that bubbled over a year earlier at Eastwood’s own wedding in Dover. 

Gemma had been wrongly accused of ‘trying to trip up’ Eastwood during her walk down the aisle.  

Neither Eastwood nor her husband – previously Ken’s best friend – were invited to the May 2024 nuptials.  

The paint caused more than £5,000 in damage to the registry office and specialist cleaners were unable to save Gemma’s dress, which she had hoped to hand down to her daughter. 

At Maidstone Crown Court, Gemma read a powerful victim impact statement. She described how the attack had shattered her mental health

‘To have paint thrown over me by my brother’s wife changed my outlook on life,’ she told the court. ‘I have lost who I used to be.’ 

Antonia Eastwood pleaded guilty to criminal damage after throwing black paint over her sister-in-law's wedding dress. The mum-of-two was subjected to the spiteful ?revenge? attack witnessed by horrified wedding guests invited to see Gemma and Ken Monk tie the knot at Oakwood House Register Office in Maidstone. Antonia Eastwood, who is married to Gemma?s older brother, Ashley, fled the venue, leaving her splattered victim in tears. Remarkably, Gemma, 35, pulled herself together, scrubbed her face and body in a changing cubicle and borrowed a dress fetched by an usher to marry her partner of more than 20 years.

The trauma was compounded by the fact that Gemma was undergoing a cancer scare at the time. Eastwood was allegedly aware of the medical issue when she planned the attack. 

Gemma has since been given the all-clear. However, the emotional toll forced the couple to cancel their dream honeymoon to the Maldives

Prosecutor Pietro Matarazzo noted that Eastwood initially gave a ‘no comment’ interview to police. She later admitted to a probation officer that it was a premeditated revenge attack. 

Judge Oliver Saxby KC did not hold back his contempt for Eastwood’s actions. He dismissed her claims that the incident was a ‘spur-of-the-moment’ error. 

‘You got it into your head that you wanted to wreck her day,’ the judge said. ‘And you did, and it was horrid and nasty and mean.’ 

The judge acknowledged that while emotions were high, he had to follow sentencing guidelines. He cited prison overcrowding and Eastwood’s previous good character as reasons to suspend the sentence. 

Eastwood was handed a 10-month prison sentence, suspended for 12 months. She was ordered to complete 160 hours of unpaid work and pay £5,000 in compensation. 

Gemma, who maintained eye contact with Eastwood throughout the hearing, described the sentence as ‘too light.’ She refused to accept her sister-in-law’s apology. 

The newlyweds do not celebrate their anniversaries because the date is now tied to the trauma. They plan to renew their vows in the future to create a new, untainted memory. 

Gemma is now focused on moving forward and finding her old self. ‘On that day, I managed to smile for the camera because I was marrying the man I love,’ she said.
