TROUBLED teen idol Demi Lovato has pulled out of a concert tour and gone into rehab for what were described as long-standing 'emotional and physical issues'.
"Demi decided to seek help for emotional and physical issues she has battled throughout her life," Lovato's spokesman Jesse Derris said in a statement.
Representatives for the 18-year-old star of Disney Channel's Sonny with a Chance TV show and the Camp Rock movies said last week that she was bullied in school and had a history of eating disorders and self-harm issues.
But the US celebrity media has been awash with further speculation about Lovato's sudden withdrawal from public life in the midst of a Latin American tour with pop group The Jonas Brothers.
Her troubles are seen as echoing the downfall of former Disney child actress Lindsay Lohan - currently in drug rehab for a fifth time after spending the summer in jail - and the transformation of Miley Cyrus, 17, from squeaky clean Hannah Montana star to a maker of raunchy pop music videos that have recently caused controversy.
