Jennifer Lopez is heading to Toronto to support her ex Ben Affleck’s film Unstoppable.

The movie is debuting on Friday evening at the Toronto Film Festival in Canada.

And now DailyMail.com has learned that the 55-year-old movie star is happy to do so.

‘Jennifer if excited to head to the Toronto Film Festival to promote this film because Unstoppable means a lot to her, she wants to support it,’ a source told DailyMail.com.

‘It is a true life story that is very inspirational and she is proud to be a part of it. Acting in the movie was a high point for her.

‘The movie has been getting a lot of attention and Jennifer wants it to do the best it can. She is very professional and always works hard to give her movies their best opportunities.’

Lopez has a supporting part as a wrestler’s mother in the movie, which already has Oscar buzz.

At the premiere, Lopez will dress up with her usual flair in high heels and diamonds.

‘She will have several friends with her and of course her glam squad, but it will be a quick trip,’ said the source. ‘She won’t be in Toronto for very long as she has other matters to attend to.’

Jennifer filed for divorce from Ben last month after two years of marriage.

Affleck, along with pal Matt Damon, are the ones who oversaw the movie as Lopez has a supporting acting role.

Lopez also co-produced the project with her producing partner Elaine Goldsmith-Thomas.

Affleck will not be present at the Unstoppable premiere, according to PageSix.

The film will be shown in the Special Presentations section at the Toronto International Film Festival, followed by a limited theatrical release in December 2024, by Amazon MGM Studios.

Certain producers on the movie were trying to ‘pushing the two to appear together at the premiere in Toronto to create buzz on the film,’ DailyMail.com reported earlier this week.

But those producers did not get their way as now only one of them will be there.

The project is from Ben’s production company Artists Equity, which he co-founded with longtime friend Damon.

Affleck and Damon, 53, are among the 14 producers on the film.

The Amazon MGM Studios film wrapped production this past January.

Jennifer and Ben separated in April.

The couple previously starred together in Gigli (2003) and Jersey Girl (2004). And he also appeared in her film This Is Me… Now as well as her docu The Greatest Love Story Never Told.

Unstoppable centers around the life of wrestler Anthony Robles, who was born with one leg and won a national championship in 2011 while competing at Arizona State University.

Actor Jharrel Jerome (Moonlight) plays Robles and the supporting cast includes Bobby Cannavale, Don Cheadle and Michael Peña.

Unstoppable is directed by William Goldenberg, who previously worked with Affleck as an editor on his 2023 movie Air, as well as Argo (2012).

Ben and Jennifer have another movie they worked on together: Kiss Of The Spiderwoman.

It is based on Manuel Puig’s novel of the same name, and is set in an Argentinian prison in 1981. Lopez stars as the titular role, a fantasy woman named Aurora created by Luis Molina (Tonatiuh), a gay hairdresser serving an eight-year sentence for allegedly corrupting a minor.

Affleck and Damon are among the co-producers through Artists Equity.

Affleck was asked by CBS Sunday Mornings in March 2023 about collaborating with Lopez on the film.

‘What fun, what a joy to do something with her, see her be great, go to work with your wife, go to work with your best friend,’ he said.

‘If you don’t like who you’re working with, and if you have difficulty or trouble at work, I think it’s one of the things that can really cause depression, anxiety and pain for people,’ he added at the time.

‘And conversely, [if] you love the people at work, you probably have a pretty good life, you know?

‘Can’t make it look like she’s doing it as a favor to me, but actually she is,’ Affleck also said during the interview.

Ben and Jen wed in Las Vegas in July 2022.

Asked by Variety earlier this year whether she and Affleck would ever star in another movie together, Lopez said, ‘Maybe, in the right thing.’

‘I mean, we love working together and being together, so maybe,’ she added.

Ben was last seen on Tuesday morning with his ex wife Jennifer Garner and kid Fin. They were returning from taking their eldest child Violet, 18, to college.

Hours later Lopez filed for divorce. It was her two year wedding anniversary with him.
