Ben Affleck has hailed Jennifer Garner as a "spectacular" mother of their children.

The 54-year-old actor has Violet, 20, Seraphina, 17, and Samuel, 14, with Jennifer, his ex-wife, and Ben has joked about his own parenting skills in comparison to the actress.

During an appearance on Sunday Today with Willie Geist, Ben - who was married to Jennifer between 2005 and 2018 - explained: "Their mom is spectacular, and it always makes me feel like I'm coming up a little short."

Ben joked that he tells his kids that he's "doing about 75 percent as good as [their] mom".

The Hollywood star added: "They're like, 'Maybe 40 percent'. I'm maxing out. Woo, B+!"

Ben subsequently explained that in spite of their break-up, he's retained huge respect for Jennifer and her parenting skills.

The actor-turned-director - who was married to Jennifer Lopez between 2022 and 2025 - shared: "I respect her. I think the most important thing is having that mutual respect -- being able to get along with that person."

Earlier this year, Jennifer also heaped praise on Ben, describing her ex-husband as an "incredible co-parent".

The actress told Entertainment Weekly in July: "My kids are a little bigger [now]. Their dad … has become this incredible coparent. And I have this unbelievable [business] partner who produces with me things that we control and are able to help keep in L.A. … I love making movies anywhere, but I really want to make movies at home."

Jennifer subsequently hailed Ben as a "great" co-parent.

The movie star said: "He's wonderful. He takes care of them. He's a great partner in that way. And that's very freeing."

Prior to that, Ben explained why he separates his work from his personal life.

The actor also described divorce as an "excruciatingly painful" experience.

He told USA Today newspaper: "I know there's a tendency to watch actors - particularly when you have a lot of things you associate with the actor, that's sort of our baggage -- and sort of project those things onto them.

"The truth is, really, it's not as correlative as you would think, except for the sense that you've got to have lived life to be able to relive it authentically.

"The circumstances of divorce with children is facing something that's excruciatingly painful. People can identify with that if they've been through it. And as an actor, it's your job to find something that's related to that.

"Weirdly, as an actor, if you actually think about the exact moments that correlate to the exact thing, it's too literal, and it sort of doesn't work."
