Singer Selena Gomez, who recently completed a two-week stint at a rehabilitation centre, volunteered for it, said her representative.
The 21-year-old was admitted to Dawn at the Meadows in Arizona, which treats young people struggling with emotional trauma, addiction or dual diagnosis concerns.
"Selena voluntarily spent time at Meadows but not for substance abuse," eonline.com quoted the representative as saying.
The singer cancelled the Australian leg of her Stars Dance tour in December last year as she wanted a break.
