Zac Efron Pumping Gas... And a Whole Lot More

Zac Efron swirls his car keys around and flashes photographers a rare smile as he pumps gas into his dented Oldsmobile Alero at a Beverly Hills gas station on Saturday. (He wore a “MATE OF STATE” t-shirt, supporting the American indie rock duo).

The 19-year-old High School Musical star has recently been tapped to host the 2007 Nickelodeon Australian Kids Choice Awards in October, along with sister singing duo The Veronicas.

“I’m so excited to be coming to Australia to host Nicks Kids Choice Awards,” Zac said. “I can’t wait to get down there and slime all the Aussie kids – it’s going to be a blast.”

Zac and his High School castmates are expected to open tonight’s Teen Choice Awards. Tune in tonight @ 8PM ET/PT on FOX!
