Photos of Matthew Perry, Zac Efron, the Jonas Brothers, Vanessa Hudgens, Corbin Bleu, Seth Green & More At US 17 Again Premiere

Matthew Goes Back In Time With Zac and His High School Pals

While we had our UK premiere of 17 Again back in March, the US premiere took place last night in LA, with stars of the movie Zac Efron, Matthew Perry, Leslie Mann and Michelle Trachtenberg getting dressed up and taking to the red carpet. Zac's past costars also showed their support for the movie — his High School Musical buddies Corbin Bleu, Olesya Rulin and Monique Coleman showed up with Zac's girlfriend Vanessa Hudgens, and his Hairspray costars Brittany Snow and Amanda Bynes also attended. Tween favourites the Jonas Brothers also added to the Disney star quota, and no doubt had plenty of fans outside the cinema screaming their names as well as Zac's! Looks like the event really was a teen dream!

To see more photos from last night's premiere including Amanda Bynes, Brittany Snow, Judd Apatow, Michelle Trachtenberg, Leslie Mann, Seth Green (and his new mohican) and many more, just read more.
