Oscar-winning actor Ben Affleck celebrated his 41st birthday at his home with family and friends. "There were about 30 people who showed up around 2 pm for an afternoon party. There were kids running around in the yard having a blast. "It was a relaxed afternoon and people didn't bring gifts. They all started to leave after dinner around 6 or 7 pm," a source said. The house party,organised by the actor's wife Jennifer Garner,was attended by Matt Damon with his wife Luciana and four daughters. Affleck recently replaced Christian Bale as Batman and will make his first appearance as the caped crusader in the Zack Snyder directed "Man of Steel" reboot.
