15 APRIL 2009 It was a sight to set young female hearts racing - High School Musical hunk Zac Efron and teen musicial siblings the Jonas Brothers all in the same vicinity. The dishy American bandmembers were kicking back at a bash to celebrate the launch of Zac's new movie 17 Again.
Blue-eyed swoon-meister Zac appears opposite Friends actor Matthew Perry in the new comedy, which follows an unhappy middle-aged man whose world is turned upside down when he miraculously reverts to being 17 years old.
Zac says he was "flattered" to portray the teenage version of Matthew in the movie. "He's a comedic icon and I was very excited when he signed on to do the movie because I could imagine what he could have been like as a teenager," says the 21-year-old.
Before partying with Jonas siblings Kevin, 21, 19-year-old Joe and Nick, 16, Zac attended 17 Again's LA premiere. With his actress girlfriend Vanessa Hudgens absent the actor took to the red carpet with co-star Michelle Trachtenberg.
