The Jonas Brothers made an appearance at the Gibson Amphitheater at Universal Studios for a charity concert event Sunday, where they practically sent fans into a tizzy at the mere sight of them!

They stepped outside to greet fans and sign autographs, but when a particularly vocal group of little girls (and boys?) started a chant of "come over here!", they happily obliged!

Guess no matter how big they get, the boys will always remain true to their fans!
