Zac Efron spotted sunbathing with girlfriend

Melbourne (ANI): High School Musical's Zac Efron may have left his Sydney fans gasping when he was spotted sunbathing with his co-actor girlfriend Vanessa Hudgens in the Harbour city. The 20-year-old, who arrived in the city ahead of the Disney franchise's premiere, was reportedly seen flexing his muscles while his love interest and 'High School Musical 3' co-star Ashley Tisdale clenched hands during a short water taxi ride back to their hotel.

Dubbed as 'the new American heart throb' by the Rolling Stone magazine, Efron is said to have insisted on categorising himself as a 'serious actor' despite his young appeal. The actor-singer also scored brownie points when he impressed fans with his voice in the film version of the Broadway musical 'Hairspray', reports the Daily Telegraph.
