It's true. Way back in 2007, Chris appeared on season four of "The O.C." as Will Tutt, a lonely band geek who befriends Kaitlin Cooper.
Regarding his role, Chris said at the time, "I play, like, a band geek -- I'm really stepping out of my own character. I was kind of a geek in school, grade-wise. But style-wise, I was always popular and cool."
He played the drums on the show. Or, the drum, I guess.
