Jason Biggs Insider Shares New Details Behind Heartbreaking Split From Jenny Mollen

Jason Biggs and Jenny Mollen reportedly dealt with issues in their marriage for some time before confirming their separation earlier this month.

According to the Daily Mail, a source close to the couple claimed that Biggs’ recent weight-loss transformation and the stress tied to his career contributed to tension in the relationship.

“Jason definitely has changed since his weight loss transformation. He lost a lot of weight and it definitely helped boost his ego,” the insider told the Daily Mail.

“I don’t think he was wanting to lose that much weight but it happened and he’s proud of the results like anyone who lost 40 pounds or more would be,” the source added.

During his April 2025 interview with Page Six, Biggs revealed that health concerns pushed him to change his diet and workout habits.

“I had some cholesterol issues,” Biggs explained at the time.

After making adjustments to his routine, the actor said his “cholesterol came down 70 points.”

The Daily Mail source claimed the physical transformation also coincided with a stressful period in Biggs’ career.

“He had his first big directorial debut [‘Untitled Home Invasion Romance’] last year, and that was a really stressful time for him,” the insider said.

“Trying to remain in the spotlight and continue to put out projects that are just as entertaining as what he was known for previously can be a difficult task,” the source continued.

“But he has this reputation and he knows that and he puts pressure on himself to do things that are going to get just as much attention. Jason has had more stress in his life than Jenny lately and I think that’s definitely caused a bit of a wedge.”

Biggs is best known for playing Jim Levenstein in the “American Pie” franchise between 1999 and 2012. More recently, he directed “Untitled Home Invasion Romance” and appeared as himself in the Prime Video comedy “Operation Taco Gary’s.”

The Daily Mail source also claimed Biggs and Mollen attended couples therapy before deciding to separate.

“They were truly a team,” the insider told the outlet.

The source added that the pair had experienced growing “issues” for “a while now,” but therapy reportedly helped them stay together longer.

“I think if they didn’t do therapy, they would’ve split maybe two or three years ago,” the insider claimed.

A representative for the couple confirmed the separation to People on May 14. According to the outlet, the pair remain on “great terms” and are focused on coparenting their two sons, Sid, 12, and Lazlo, 8.

A source close to the family also told the outlet that Biggs and Mollen recently celebrated Biggs’ 48th birthday together.

“They are very much connected,” the source said of the pair’s future as coparents. “I have no doubt that they will remain on excellent terms.”

Biggs and Mollen first met while working on the 2008 movie “My Best Friend’s Girl.” They became engaged in January 2008 before eloping that April. Later that year, they held a second wedding ceremony in Napa, California, with approximately 40 guests attending.

Mollen has built a career as both an actor and author. She appeared in projects including “Crazy, Stupid, Love,” “Girls,” “Wilfred,” and “Chicago Fire.” She also became a two-time New York Times bestselling author with her books “I Like You Just the Way I Am” and “Live Fast Die Hot.”

Most recently, Biggs and Mollen both appeared in the comedy “Influenced,” which is currently in theaters.
