Matt Damon: My Whole Family Knows 'Gangnam Style'!

Matt Damon is all smiles as he arrives on a flight at LAX Airport on Thursday (August 15) in Los Angeles.

The 42-year-old Elysium actor arrived back from South Korea, where he promoted his new sci-fi flick.

“Everyone in America knows it’s a huge [film] market and a growing market. I wasn’t surprised when I was told by the studio that I was coming here. I hope next time I can bring my family here,” Matt said (via THR) at a press event for the film about South Korea. “I have four kids so believe me, we all know ‘Gangnam Style.’”
