Racy Photos of Demi Lovato Leaked OnlineIt's been quite the year for teen stars: From Miley Cyrus' salvia scandal to Taylor Momsen's never-ending stream of raunchy quotes, young celebrities seem to be acting out -- and recording their indiscretions -- more than ever.

Demi Lovato has been no stranger to drama this year, landing in rehab after a blowout with a backup dancer, and now, provocative pictures of the Disney star are making the rounds online.

The Superficial has published photos of Lovato flashing her cleavage while her backup dancers, including Alex Welch, who she allegedly assaulted, look on and pose seductively with the star. In one photo, Lovato poses alone in a lacy bra while smiling for the camera. (See More Pics From The Superficial.)

While rumors that Lovato is suffering from a drug problem have surfaced, sources close to the star say that her issues are much more innocent.
