Did Kevin Jonas Flip for Brother Joe? (VIDEO)

Well, this is very un-Disney-like behavior.

Video footage of a recent Jonas Brothers concert has emerged, in which Kevin Jonas appears to give brother Joe Jonas the one-finger salute onstage as they crossed each other’s paths, apparently in more ways than one.

Does Kevin share Demi Lovato’s dismay over Joe’s decision to bring his girlfriend, Ashley Greene, on tour with him? Or was Kev just reminding his sib that they’re number one?
