The Jonas Brothers Rock Radio One

The Jonas Brothers sign autographs and take pictures with fans outside the Radio One Studios in London on Tuesday (May 12).

Kevin, Joe and Nick helped promote their upcoming album Lines, Vines, and Trying Times, set for a June 16 release.

FYI: JB makes a special surprise appearance in the new film Night At The Museum: Battle Of The Smithsonian, and the brothers are set to walk the red carpet at the movie’s premiere in Washington, D.C.!
