Zac Efron arrived at Los Angeles International Airport on Thursday evening to catch a flight out of town, and the actor wasn't too chatty with photogs, but when one of our videographers asked the sexy star if he was bisexual, we definitely got a reaction out of him!

After being asked about his relationship with Michelle Rodriguez, who dates ladies and gentleman, the former High School Musical hottie was asked if he swings both ways and he laughed it off. At least he's got a sense of humor about it!
