It's not just an act; the Jonas Brothers really are BFFs, y'all.
At the Hollywood premiere of Jonas Brothers: The 3D 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?
Selena Gomez or Camilla Belle (whom Nick and Joe are reportedly dating) were nowhere in sight.
Instead, Joe answered: "The whole family's here...(security guard) Big Rob's here...our band's here."
And don't expect to see Demi Lovato, who starred with the boys in Camp Rock, on their arms for any premieres.
Although the Disney star stepped out to support her friends, when asked which one she'd date, she said the thought was—brace yourselves!— "disgusting."
