demi lovato alex welch Demi Lovato's final straw? Punching 'Dance Crew' contestant Alex 'Shorty' Welch

The unfortunate circumstances around Demi Lovato’s decision to leave her current tour with Jonas Brothers and seek treatment for a number of “emotional and physical issues” continue to involve more parties.

TMZ reports that the “Camp Rock 2” and “Sonny With a Chance” star made the call to address her unstable situation after an altercation with a backup dancer touring with the Jonas Brothers.

Alex ‘Shorty’ Welch, a member of the Season 3 “America’s Best Dance Crew” troupe Beat Freaks, reportedly received “a pretty nasty shiner” from a fight with Lovato and is currently in talks with lawyers about taking the matter to court.

The story also claims that sources close to Lovato say that it was this incident that made her call her behavior into question and that she feels “awful” about the fight.
