Joe Jonas and Camilla Belle have broken up.

And he's crying about it. ONSTAGE!

Brad Cafarelli, Belle's rep, confirmed the split to People, "There is no third party involved and they care deeply about each other and will remain friends."

The young rock star was reportedly weeping during a Jonas Brothers concert in Detroit last night, singing "Much Better," a song he penned after starting to date Belle last fall.

The song is about a girlfriend who is better than a previous love. The song is thought to be a dig at Taylor Swift, who dissed Jonas for breaking up with her ON THE PHONE!

Some fans reported that Joe cried through his “Gotta Find You” and “Turn Right,” a song off their new album.

He also reportedly changed some song lyrics. In one song, it went  from "Now I see everything I'd ever need is the girl in front of me" to "… girls in front of me," suggesting he’s in the market again.

During "Much Better," he changed the lyrics from "Get a rep for breakin' hearts, now I'm done with superstars" to "Get a rep for breakin hearts, now I'm done with movie stars.”

Ouch.

How’s it feel to have your heart broken, Joe?

Hope Camilla broke up with you in person and not on the phone.

That is supposed to be a real downer. Or that's what we hear.

Are you happy Joe is single again? We always thought Miss C was way too old for him anyway. Did you?
