Zac Efron is a Burbank Boy

Zac Efron catches a departing flight out of Burbank Airport with younger brother Dylan and some friends in Los Angeles on Thursday morning. (Of course Zac‘s pants ride so low, you can see his underpants!)

Check out the Access Hollywood video below of Zac passing flirty glances to girlfriend Vanessa Hudgens in a behind-the-scenes video of their September 2008 Elle magazine photo shoot. You see Zac being very playful and affectionate towards Vanessa, even swinging her around in his arms. Watch the clip below, a fashion nod to 1978′s Grease!
