Jennifer Lopez is allegedly very protective of her relationship with Ben Affleck.

An unnamed source told National Enquirer that Lopez is not a fan of Affleck’s best friend, Matt Damon. After all, every time the besties hang out, Lopez worries that her fiancé tells Damon everything about their relationship.

“Jennifer doesn’t much care for Matt or his wife, Luciana. They’ve socialized on very few occasions and it’s tended to be awkward mainly because Jennifer can’t stand not being the center of attention,” the source said.

The insider claimed that Lopez believes Affleck is most comfortable sharing their issues with Damon. After all, they’ve been friends for years.

“Jennifer suspects Ben’s using Matt as a sounding board to bitch about her. She’s checked them out on the set and grills Ben about what they talk about when he gets home. Maybe that’s why Ben tends to hang out on set longer than necessary. He doesn’t want to face the harpy at home,” the source said.

This isn’t the only rumor surrounding Lopez and Affleck as of late. Last week, Globe claimed that Lopez refuses to play nice with Affleck’s ex-wife, Jennifer Garner.

The source claimed that Affleck and Garner are good friends and co-parents to their three children. So, if it’s up to him, he wants Garner to be part of his life. However, Lopez insisted that this cannot be the case.

“Ben knows they’ll never be one big happy blended foursome, but he’d appreciate it if J.Lo wasn’t so bitchy and disinterested in any type of interaction with Jen and her man. Whenever he nips off to pick the kids up and stay for a coffee, he comes back to the third degree from J.Lo,” the source said.

However, one should take the tabloid’s claims with a grain of salt. As of late, there’s no proof that Lopez doesn’t want Affleck to hang out with Damon.

In fact, Damon was one of the people who shared his thoughts about the A-listers getting back together. And he made it clear that he supports Affleck and Lopez’s relationship.

As such, there’s no reason for Lopez to dislike Damon or to ban Affleck from hanging out with him.

It’s not also true that Lopez dislikes Garner or that she doesn’t want the Alias star to be part of Affleck’s and their kids’ lives.
