Specific details surrounding the 18 year old's decision to enter an undisclosed medical facility have not been revealed, but America's Star magazine claims the sudden passing of aspiring rocker David Osborn contributed to her troubles.
Osborn drowned in the Brazos River after an accident in late July and Lovato paid tribute to the 21 year old on her Twitter page a week later. She wrote, "Can't wait to see you again in heaven... Texas isn't the same without you... RIP Dave Osborn."
The star is alleged to have embarked on a fling with Osborn in March after attending a mutual friend's house party in Texas. The rumored romance followed Lovato's split from pop star Joe Jonas earlier this year. Meanwhile, a representative for Lovato has moved swiftly to shoot down rumors the troubled teen is pregnant.
DJs at a Salt Lake City, Utah radio station sparked the gossip on Wednesday morning, November 10 but her spokesperson tells TMZ the claims are "100 per cent not true".
