GSI 1 / 14

Estranged husband and wife Ben Affleck and Jennifer Garner put their differences aside over the weekend in the interest of spending some family quality time together with their daughters, Seraphina, 7, and Violet, 10.

Carrying a pizza box and looking relaxed in jeans and a gray T-shirt, Jen was photographed leading the foursome through a parking lot in Santa Monica, Calif. and chatting with her ex before grabbing a sweater for him out of her car.

Ben flashed a smile at one point while flanked by the colorfully clad little girls as he and Jen headed for their cars.

Between their commitment to co-parenting their kids and their work responsibilities during awards season, the actors have been maintained a sense of civility while sharing one another's company a handful of times in recent weeks.

Last month, they held a superhero-themed birthday party for their son, Samuel, who turned 4.

And after they both attended the Academy Awards on Feb. 28, they made separate appearances at the Vanity Fair afterparty, although Ben reportedly left soon after Jen arrived.

His early departure was understandable; that week, the magazine published an interview with the "Alias" star in which she got candid for the first time about Christine Ouzounian, the nanny Ben was rumored to have become romantically involved with prior to his and Jen's split.

"We had been separated for months before I ever heard about the nanny," Jen told Vanity Fair.

"She had nothing to do with our decision to divorce. She was not a part of the equation. Bad judgment? Yes. It's not great for your kids for [a nanny] to disappear from their lives. I have had to have conversations about the meaning of 'scandal' [with the children]."

Despite the nanny complication, Jen assured the magazine Ben was her soul mate, saying she had no regrets about marrying him.

"I ran down the beach to him, and I would again," she said. "You can't have these three babies and so much of what we had. He's the love of my life ... He's just a complicated guy. I always say, 'When his sun shines on you, you feel it.' But when the sun is shining elsewhere, it's cold. He can cast quite a shadow."
