Jennifer Garner Tells Us About Ben Affleck’s 'Best Dad Moment in History'

After a tough personal year, Jennifer Garner is back on the big screen in the emotional new movie, “Miracles from Heaven.”

Jen sat down with “Extra's” Renee Bargh for the first time since her Vanity Fair tell-all in which she talked openly about her very public divorce from Ben Affleck.

Garner, who was joined by 12-year-old co-star Kylie Rogers, told Renee about her youngest son Sam's 4th birthday bash over Oscars weekend.

Sam asked for a superhero party, and Jen explained, “We all dressed up, I dressed up as a ninja, and Ben dressed up as Batman for Sam, which was the best dad moment in history,” adding, “It was pretty sweet.”

Kylie, who called Garner a “magical mom” on social media, told Renee that Jen is so good to her kids, “She's sweet.” When Renee asked Jen if the kids know she is famous, she said, “They have an understanding of what their parents do for a living and they get it… we just talk about the pros and cons.”

Jen said when times get tough for her, she relies on her friends. “My girlfriends for sure, and they're everything, and I include my sisters in that… I think I'm so lucky to have grown up with two sisters because I make my girlfriends my sisters and I make my sisters girlfriends.”

The actress hit the Vanity Fair Oscar party with one of her girlfriends. “I had a great time, I went with one of my very best girlfriends. We've gone together maybe eight times, so we have a whole routine and we had a blast!”
