Kevin Jonas has declared there is "nothing there" between his brother Joe and Demi Lovato. Joe and Demi play boyfriend and girlfriend in forthcoming film Camp Rock 2, but Kev insists the romance is only on screen.

"There's rumours going around but I can assure you there's nothing there - but in the film the love story between Mitchie and Shane continues for sure," he said. The brothers are touring the UK at the moment and took some time out to give British school children a special music lesson.
