Someone has claimed that Demi Lovato does drugs!

A source has claimed that Demi Lovato has a drug problem!

Demi recently checked into rehab to “seek medical treatment for emotional and physical issues she has dealt with for some time” according to her rep – well apparently this has caused Demi to drink and party.

On December 28 2009, Demi reportedly hung out with a group of students in North Richland Hills, Texas, where she was seen allegedly doing cocaine.

“She was doing line after line like a pro — and she was 17 at the time,” Texas college student Brian Payne told America’s Life & Style magazine.

“I just remember her doing it as if she had been doing it for a long time. It didn’t seem like something new to her.”

Demi Lovato? Really? What do you make of these claims? Leave us a comment.
