The Jonas Brothers Sing "PLEASE BE MINE!" (BOP & TIGER BEAT)

As if watching the Jonas Brothers perform "L.A. Baby" and "Can't Back Down" weren't amazing enough, the boys treated their fans by serenading them with a fan fave song, "Please Be Mine!" Watch the video to see what Joe had to say before he, Nick and Kevin melted the hearts of every girl in the audience! We loved it!
