Zac Efron was seen shirtless on his balcony showing off his great body.

It seems that Efron graduated from his boy next door image and now ready for leading man roles. Now, he is all about biceps and a flat stomach.

The 24-year-old actor was photographed by a paparazzi stuffing his bag with essentials without his shirt off. Zac Efron also graced the cover of Men's Health magazine, where he showed off his newly-sculpted body that makes a lot girls drool.

The former High School Musical star arrived to Sydney for the red carpet premiere of his new flick "The Lucky One" where he was welcomed by screaming fans.

The movie "The Lucky One," a romance film directed by Australian Scott Hicks and is loosely based on the novel by Nicholas Sparks (The Notebook).

Efron buffed himself up and worked on his muscles to play Logan, a young marine corp who finds a photograph of a woman (Taylor Schilling) while fighting in Iraq. Believing that she has saved his life, he sets out to find and thank her when he returns home.

Hicks complemented the on screen chemistry of Schilling and Efron. The director said that it is "like gold dust" for him.

Taylor Schilling was unable to make the world premiere in Sydney because she was ill, but is expected to be at the premieres in Melbourne and Hick's hometown of Adelaide.
