People confirmed that Gomez checked herself into a rehab center for two weeks in January, but reps for the 21-year-old said she was not struggling with drugs or alcohol.
Gomez was admitted to Dawn at the Meadows in Arizona on Jan. 5. Although the center treats people for many addictions, it's not clear what Gomez was being treated for.
"Selena voluntarily spent time at Meadows but not for substance abuse," Gomez's rep told People.
Gomez's Australian fans were upset when she canceled that leg of her Stars Dance Tour, but she said it was important that she took a break after years of touring and working.
"It has become clear to me and those close to me that after many years (of) putting my work first, I need to spend some time on myself in order to be the best person I can be," she said in a statement at the time.
Gomez has been around many addicts in the past — some who have gotten help for themselves and some who haven't. Just after the new year, and just a few days before checking herself into the rehab center, Gomez was spotted hanging out with her ex-boyfriend Justin Bieber.
