U.S sensations The Jonas Brothers unleashed their brand of high-energy pop-punk on an excitable crowd at London's O2 Arena on Wednesday.

The day-glo siblings - Nick, 16, Joe, 18, and Kevin, 20 - are currently supporting Avril Lavigne on her European tour but were in serious danger of upstaging the headline act with last night's energetic live show.

But their whirlwind stay in the U.K hasn't been without its challenges - as this clip of the brothers getting to know their London hotel room clearly demonstrates.

The Jonas Brothers release their first U.K single S.O.S on June 15, with their 1.4 million-selling self-titled debut album to follow on June 23.
