Matt Damon showed up at LAX International Airport last night (June 24).

Joined by his wife Luciano Barroso, the “Good Will Hunting” hunk was greeted by a swarm of fans and stopped to sign autographs as he made his way through the terminal.

In a recent interview, Damon shared that he quit his pack-and-a-half smoking habit back in 2004 when he and his bride decided to start having children.

“I remember my brother gave up before he had kids and he said, ‘I'm going to give myself six months or a year to clear out my system before I, you know...’ Whether there's any wisdom to your sperm-carrying, your system being somehow cleaner, but that was his thing and I remember thinking, ‘Yeah, I'll do that, too.’”

As for how he began smoking, Matt noted, “Ben [Affleck] and I started when we were in high school. We'd see the great actors - [Marlon] Brando, James Dean, Mickey Rourke- who we loved back then - smoking, and we just thought it was f***ing cool.”
