It's not just an act; the Jonas Brothers really are BFFs, y'all.
At the Hollywood premiere of Jonas Brothers: The 3-D Concert Experience last night, Kevin, Joe and Nick insisted they're all really close.
"When it comes down to it, truthfully, we're best friends," Joe told E! News. "We love being together."
With a travel and tour schedule like theirs, do they really have time for other friends, anyway?
And what about the boys' dates for their big night?
