I'm too lazy to go look for further Internet-based evidence but E! reported that CAMILLA BELLE AND JOE JONAS HAVE BROKEN UP.

Ok, buster. First I thought, grudgingly, that you and Cam were better suited than you and Taylor, and Taylor was better off without you anyway. Then after a while I decided I might like Cam a little bit anyway. AND NOW YOU BREAK UP WITH HER. Whose heart are you going to break next? It better not be one of my favourite actresses or I'm gonna have a word with your mother!

I once read that the Jonas brothers' room or something was called the Players' Lounge and now I see that it's absolutely right. Emma Roberts is right for swearing off Jonas brothers.
