"X Factor" judge Demi Lovato recently booted two auditioning rappers off stage for lyrics about using bath salts, but there are sources who claim the singer isn't quite living the sober life herself.
A source told RadarOnline that despite a three-month stay in treatment for emotional and physical issues -- including eating disorders, self harm and drug use -- she's still "partying hard behind the scenes."
Since she left Timberline Knolls treatment center in January 2011, Lovato has become the veritable poster child for eating disorder awareness and has spoken candidly about her bipolar diagnosis and drug use, but Radar's source says, "[Lovato is] not as sober as she's leading everyone to believe and is still partying hard."
A second source also told the website that the former Disney star hasn't quit partying, but she has learned from past mistakes and knows to make sure the paparazzi don't catch her in the act.
When asked for comment, Lovato's rep denied the allegations, telling The Huffington Post in an email that the claims are "total bs."
Lovato hasn't been shy when talking about her recovery and what led her to treatment in the first place. In April she explained that her celebrity status provided her with easy access to drugs, telling Fabulous Magazine:
"[Club] promoters gave me drugs and alcohol in restaurants or clubs,” she said. “They wanted me to come back so I would be seen there. They were basically kissing my ass. Being a celebrity can be dangerous. Nobody says ‘no’."
It's been well over a year since Lovato completed treatment, and though she's admitted that she still struggles with her bulimia and cutting, she says she's completely clean and sober.
"I'm not gonna lie. I was self-medicating," she told Seventeen magazine in January. "I was doing things like drinking and using [drugs], like a lot of teens do to numb their pain. [But now] I don't drink, I don't do drugs."
This month, Lovato appears on the cover of Self magazine and further opens up about her problems.
"There were times I felt so anxious, almost like I was crawling out of my skin, that if I didn't do something physical to match the way I felt inside, I would explode. I cut myself to take my mind off that. I just didn't care what happened. I had no fear," she told the magazine.
Lovato says she's completely changed her life around, telling Self:
"I surround myself with people who make positive decisions and who have more interests than wanting to go to clubs and get wasted. My friends and I look out for each other, and I love just inviting everyone over to watch TV. I like 'Law & Order'—except it makes me want to go out and inspect everyone on the street to see if they're a serial killer!"
