Zac Efron - Oscars 2010 Red Carpet

Zac Efron looks dapper in a Calvin Klein suit as he arrives at the 2010 Oscars held at the Kodak Theater on Sunday (March 7) in Hollywood, Calif.

The 22-year-old High School Musical actor arrived solo to the event, but USA Today caught up with the actor who said he’ll be meeting his girlfriend Vanessa Hudgens later.

At the event, Zac arrived at the same time as Avatar‘s Sam Worthington.

According to MTV, Zac joked with Sam about all the 3-D technology involved with his movies and said “I’ve seen you in every possible D, man!”
