Hundreds of screaming fans came to meet The Jonas Brothers at the European premiere of Camp Rock, and we were screaming with them!

Check out our exclusive pics from the red carpet and a personalised message from the Jonas Brothers themselves!

The premiere was a star-studded affair and guests included Jaime Winstone, The Saturdays, Brad Kavanagh, Avenue and even...Jason Donovan!

London's Royal Festival Hall was transformed into a musical camp for the night - after the film screening, Demi Lovato and The Jonas Brothers performed songs from the film including This Is Me and Play My Music.  We were treated to cupcakes and delicious strawberry punch, but best of all, we saw a preview of High School Musical 3 - be prepared girlies, it's gonna be a good 'un!

High School Musical 3 star Jemma McKenzie Brown walked down the red (well, purple actually) carpet looking glam in a black ruffle dress and killer heels.  Jemma is a fab new addition to the cast and appears as Sharpay's personal assistant - better watch out!
