Jennifer Garner reportedly wants Ben Affleck to end his friendship with Matt Damon. The Daredevil star feels The Martian actor is a 'bad influence' on Affleck.

An alleged source told National Enquirer: "Jennifer can't stand Matt and blames him for many of the problems that drove her and Ben apart this past year."

"Matt has influence over Ben. Matt has Ben's ear. Ben tends to do Matt's bidding. Jen feels resentful. She may forgive, but she won't forget. Matt's in Jen's little black book of undesirables. Matt will always defend Ben, no matter what he's done and even if he's wrong," the insider added.

"In Jen's book, that makes him no friend of hers," the source continued.

The 44-year-old actress and the Argo actor have remained close, though they announced their divorce in a joint statement on 30 June 2015 — a day after their tenth wedding anniversary.

Previously, Affleck had talked about his successful co-parenting with Garner. He told E! Online: "I was doing math homework last night. When I'm there, you're stuck with your parents helping you with your homework. Jen [Garner]'s very good at math [too]. So far, my eldest kid is in fifth grade and they haven't passed me yet. But I feel like in seventh or eighth grade I'm going to start worrying that they're going to lose me."

Affleck continued: "It's important to be involved with your kids' schoolwork so you know what's going on and what they're doing and what you're supposed to be supporting and going to school nights."
