AceShowbiz - Jennifer Lopez, who recently filed for divorce from Ben Affleck, stepped into the limelight once again at the Toronto International Film Festival. She served as a producer and starred in the film "Unstoppable", playing the mother of a real-life wrestler who overcame adversity to win a national championship.

Lopez's appearance at the festival marked her first major public event since the divorce filing. A source close to Lopez revealed that she "was happy to be in the spotlight again because of work." The source told PEOPLE, "She's so over all the attention on her personal life."

Despite being a producer on the film, Affleck notably did not attend the premiere. However, Matt Damon, Affleck's longtime friend and co-producer, did attend and was seen spending time with Lopez. The two shared a lengthy conversation at an afterparty, holding hands and engaging in a deep discussion.

Lopez expressed that her latest movie role felt "very cathartic" for her, resonating with her personal experiences as a mother navigating difficult relationships.

"Women who are moms who get in relationships, and you struggle with them, and you find yourself in dynamics that are not healthy, but you care about the person, love the person," she said. "That's those complicated dynamics about life that I understand really well."

Meanwhile, Affleck was spotted at work in L.A. during the event. Sources indicate that Lopez's decision to attend the festival was an attempt to move on from her failed marriage and focus on her work. She is said to be excited about promoting "Unstoppable", which she views as an inspiring story that she is proud to be a part of.
