Jonas Brothers & Demi Lovato’s tennis gig

The Jonas Brothers and Demi Lovato performed as part of the annual 2010 Arthur Ashe Kids’ Day at the USTA Billie Jean King National Tennis Center in New York City on Saturday.

Camp Rock 2 stars Joe, Nick, Kevin and Demi took to the stage and top tennis stars Roger Federer and Rafael Nadal also put in an appearance at the event.

Michael Fiur, who is the producer of the Arthur Ashe Kids Day, said: “We think it’s one of the great ways to learn, not only sports skills but life skills. For kids to become leaders, for kids to improve their education, there are all kinds of scholarship programs. So it’s really about combining sports and education through the USTA’s community tennis programs.””
