This sweet ‘remember december’ singer is probably going crazy. She deleted her Twitter account…cancled her tour with the JoBros…AND checked into rehab for treatment for what seems to be an emotional breakdown!!

Maybe it’s because she got dump by Joe Jonas!!

This actress, 18, confirmed the move in a statement issued on late Monday evening. Demi spokesfolks championed the teen star for seeking help for “emotional and physical issues” that have plagued her for months.

She fell out with childhood best friend Selena Gomez after Selena grew closer to singer Taylor Swift. And just last week, Demi went gaga on celeb gawkers (You’ll know who you are!) who insists on posting ridiculous photos of her on their blogs. Over the weekend, Demi nearly got into a knockdown dragout fight with one of the dancers on her tour. The altercation was the wakeup call Demi needed to reach out for help.

“Demi Lovato left her tour early this weekend in order to seek medical treatment for emotional and physical issues she has dealt with for some time,” the statement read. “Demi has decided to take personal responsibility for her actions and seek help. She is doing just that. [Demi] regrets not being able to finish her tour, but is looking forward to getting back to work in the near future.”

Good luck dear Demi!
