Singing stars share bodyguard but is he stealing the limelight?

A recent Jonas Brothers concert in New York revealed that the singing trio have more in common with Britney Spears than just their American roots. During the concert Brit's former bodyguard, Big Rob, took to the stage to join Kevin, Nick and Joe in a bit of a sing-along!

The meaty bodyguard - who has been hired by the brothers to keep their throng of female fans at arms length - joined in and collaborated with the boys on their hit Burnin' Up! Rob rapped on stage as the boys sang - whooping the crowd in to a frenzy!
