Disney star Demi Lovato entered a rehab facility a week ago, to deal with unnamed emotional and physical issues. Radar Online has learned a drug addiction may be the issue, with videos of the star doing lines of coke “like a pro” now making the rounds.

The paparazzi agency / celebrity gossip website claims a man approached them with videos of Demi doing drugs at various parties. Radar has not seen the videos, but believes they are genuine.

They were shot during a recent party in Texas and, Radar reports, are now being shopped to all the major media outlets, which means that, if they’re genuine, they should emerge in the following days.

“Demi was belligerent, being [expletive] and doing coke all over the house. The guy who hosted the party shot multiple videos of this and what I’ve seen [them] with my eyes,” a “friend” says for Radar.

Demi is screaming, ‘[Expletive] all of you, I’m famous, I don’t care what any of you think of me the whole world loves me.’ He shot her in the bathroom as she was finishing a line [of cocaine],” the spy further adds.

Radar also spoke to the “amateur cameraman,” who vouches the videos being shopped around are the real deal: they show the Disney star snorting lines of cocaine through a rolled up dollar bill.

As it happens, these two unnamed sources are not the only ones to come forward with first-hand accounts of Demi’s drug use, since Life&Style is running a similar story now.

“She was doing line after line like a pro – and she was 17 at the time,” student Brian Payne says for the mag. He’s talking about the same party, which took place in December last year.

“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,” Payne adds for Life&Style.

In a bid to make all these rumors go away, Lovato’s rep has issued another statement to TMZ about the reason the star is in a rehabilitation facility and, he says, it has nothing to do with drugs.

“Demi Lovato is not in treatment for drug or alcohol addiction. As we have said since she entered treatment last week, Demi decided to seek help for emotional and physical issues she has battled throughout her life,” the star’s publicist says.
