We are devastated! We're hearing that this hot teen trio may be no more! The JoBros are said to be calling it quits after a brotherly brawl broke out last night in a recording session.

CGG talked to their manager who told us all about the fight which ended in a trip to the emergency room after Nick threw his guitar at Joe's head.

The fight began over a disagreement on lyrics of their new single and ended in a battle of the brothers. But apparently there was a bigger battle boiling—the three bros are fighting over a Hollywood starlet!

Kevin broke down in tears and ran out of the studio. No one has seen him since, though one fan told reporters they saw him hitchhiking on Sunset Boulevard.

Who knew the three musketeers would ever fall apart? We are still waiting to here if they are going to return to the studio or if they will ever speak to each other again. And Joe will be sporting a mighty bandage from the serious guitar injury he endured.
