Hollywood heartthrob Zac Efron says he isn't sure if he would ever do a full frontal nude scene in a movie.
Efron was present in London for the premiere of his new film 17 Again.
On being asked if he would ever bare all for a movie the 21-year-old star said, "You look so excited. I don't know. Honestly, I don't know," reports the Daily Telegraph.
The High School Musical star had recently made headlines for posing with naked woman for magazine cover.
"It was definitely different from anything I had ever done before," he said.
