Jonas Brothers and Grandpa Take Stage Spills

Nick Jonas and his grandfather recently proved that superstardom won't protect against an embarrassing trip - or two, in this case.

During the Jonas Brothers show Saturday (Aug. 21) at the Nikon at Jones Beach Theater in New York, the boys presented a birthday cake, gift and song to their grandfather, who was turning 70. Soon after, Grandpa Jonas eradicated the sentimentality with a charming rendition of the chicken dance, which led to his backwards tumble.



And as if one toppling Jonas wasn't enough, youngest band member Nick later had a similar affair with the floor while prancing off the stage post-encore.




The Jonas boys are known for their smooth moves, but it seems that a little clumsiness may have found its way into the bloodlines of the teen heartthrob trio.
