Is Demi Lovato back in rehab? Gossip site report says yes

Demi Lovato has caused some concern amongst her fans by taking a long Twitter break following some erratic tweeting about highly personal subjects. Now, the site BlindGossip reports that Lovato has once again sought treatment for emotional and substance abuse problems.

According to their sources, Lovato has entered the rehab facility Passages in Malibu. Word is that "close friends" of Lovato (who should probably reevaluate her policy on close friends) have told the site that she's in treatment for addiction to alcohol and various drugs, including cocaine, following an intervention from her family and management team.

They say she's seeking inpatient treatment for "several weeks," and will later enter an outpatient program.

We're hoping that the rumors of Lovato falling off the wagon are false, but if she is struggling with substance abuse again, we hope she's getting the help she needs.

UPDATE: Lovato's pal Tiffany Thornton, who worked with her on the Disney series "Sonny With A Chance," tweets that the rumors are "FOR SURE" not true.
