Ben Affleck and Jennifer Garner celebrated their three-year wedding anniversary - by sitting down to dinner with actor Matt Damon and his wife.

The Daredevil stars were accompanied by Affleck's childhood pal Damon and his heavily pregnant wife, Luciana Barroso, for a two-hour dinner on the patio of Nobu in Malibu on Saturday night.

According to People.com, they ate cooked fish and sushi rolls - and toasted the couple's anniversary, which was on Sunday, during dessert.

A source says, "Ben and Matt were entertaining the girls with stories, and they were all laughing a lot."

"Jen and Ben were in a great mood, and they left Nobu hand in hand."
