In the latest 'Single Ladies' spoof, the middle Jonas brother tries to crib the diva's dance style in a new online video.

Wearing a black catsuit and matching high heels, Jonas meagrely attempts a few moves while half lip-synching to the hit song.

His brothers and band mates, Nick and Kevin, are shown at the beginning of the video prodding him to perform, saying, 'You have to do it.' The Jonas Brothers fourth album, 'Lines, Vines and Trying Times' is set for release June 16. -- AP
