Zac Efron and girlfriend Vanessa Hudgens were on the yellow carpet for the 'Watchmen' movie premiere. 21-year-old Efron ditched his usual suits and opted instead for blue jeans, an untucked shirt and a winter hat that reminded us of Robert Pattinson. Vanessa, age 20, was all legs in a super short, airy, floral printed dress with purple high heels.
