Demi Lovato Update: Sources Deny Drugs, Raise Questions Over Deceased Friend

"Demi is not in treatment for drugs. She is there to deal with emotional and physical issues she's been battling her whole life."
These are the words of family friend, shooting down recent rumors that Demi Lovato entered a rehab facility due to a problem with cocaine and alcohol.
So, is there a specific issue that forced this young singer to leave her Sorth American tour and seek help? Possibly, reports Star Magazine

In July, an aspiring musician named David Osborn died in a tubing accident. An insider claims Lovato had grown close to the rocker, who she met at a mutual friend's party in December. Soon after his passing, Demi Tweeted:

"Can't wait to see you again in heaven... Texas isn't the same without you... RIP Dave Osborn."

While it's possible the death of a loved one played a role in Demi's demise - which culminated in a physical confrontation with a backup dancer in Peru - the same source that denies this troubled star used drugs also tells People her downfall was related to a lot more than just one incident.

"This is a girl with emotional problems who has been fighting demons her whole life... She is determined to get better."
