The pair got back together in 2021 after breaking off their first engagement back in 2004 — so yeah, these two have a very long history.
Essentially, they're a dynamic duo, a lifelong pair of BFFs.
And Matt Damon — who has been married to producer Luciana Barroso since 2005 — was also a big supporter of J.Lo and Ben's relationship.
In 2021, when rumours began circling that the couple was getting back together, Matt responded by praising them: "I love them both. I hope it's true. That would be awesome."
So you'd think that Matt's closeness with Ben would mean that he wouldn't have much to do with J.Lo now that she and Ben are no longer together. Right?
BUT WE ARE MISTAKEN. Because there's a new development in all this drama, and it's HUGE. Last weekend at the Toronto International Film Festival (TIFF), both Matt Damon and Jennifer Lopez were at an afterparty for the premiere of their new movie, Unstoppable...
Meanwhile, although Ben Affleck was also a producer on the movie alongside Matt Damon, he wasn't at the premiere or afterparty.
