Damon, Affleck double date in Malibu

Matt Damon and Ben Affleck have been on a double date at the Nobu restaurant in Malibu.

The duo enjoyed a two-hour dinner at the eatery with their partners Jennifer Garner and Luciano Barroso, reports People.

A witness commented: "Ben and Matt were entertaining the girls with stories, and they were all laughing a lot."

The group toasted Affleck and Garner's third wedding anniversary during the dessert course.

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

Last week, Garner and Affleck rubbished allegations that they were on the verge of a split.
