Apparently Demi Lovato has a mean right hook! We're getting new details about her treatment and what sent her there--and it's not pretty!
According to TMZ, Demi punched Alex Welch, one of the backup dancers on the Jonas Brothers tour and gave her a pretty bad shiner. She was also a member of Beat Freaks, which got the runner-up title on season 3 of "America's Best Dance Crew."
Apparently they got into an altercation and Demi thought it would be a good idea to punch her in the face. She reportedly "felt bad" afterward and decided to take responsibility for her actions by leaving the tour and go to rehab. Either that or someone forced her to go.
Alex is now considering taking legal action against Demi, and we don't blame her! Poor girl got a nasty black eye from Demi.
