Video of Demi Lovato snorting cocaine supposedly being shopped around

(HMG Celebrity Gossip) – Yesterday news broke via Life & Style sources that Demi Lovato was also drinking and using drugs prior to her final meltdown that sent her to rehab.  Supposed insiders told L & S that her downward spiral after the breakup with Joe Jonas had lead to heavy drinking, with witnesses claiming she was “chugging booze straight from the bottle.”  And if that’s not bad enough, another L & S source claims Demi was using cocaine at a party in North Richland Hills, Texas, on December 28 last year.

“She was doing line after line like a pro – and she was 17 at the time,” Brian Payne said, recalling the wild party they attended after a concert by the band Neon Indian at the Granada Theater in Dallas.

Now a second witness at the same party is confirming that story telling RadarOnline that there is a video of Demi using coke:

“Demi was belligerent, being slutty and doing coke all over the house. The guy who hosted the party shot multiple videos of this and what I’ve seen with my eyes, Demi is screaming, ‘F**k 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).”

This all sounds pretty damning, and Radar says the video is being shopped to various media outlets. However Radar has not viewed the tape despite repeated requests, so it’s possible that the video is a fake?
