Selena Gomez's squeaky clean image is in danger this week after a report surfaced Wednesday claiming that the former Disney star spent a stint in rehab last month. 

According to a report from RadarOnline, the 21-year-old "Come & Get It" singer was treated for two weeks at the Dawn at the Meadows rehab facility in Arizona after checking in on Jan. 5. The facility, which specializes in treating patients ages 18 to 26 for emotional trauma and addiction, allegedly treated Gomez for "partying."

While Gomez has yet to publicly address the story, a spokesperson for the singer confirmed her treatment Wednesday, saying, "Selena voluntarily spent time at Meadows, but not for substance abuse."

Despite the denial of substance abuse, a source revealed to the publication that the former "Wizards of Waverley Place" actress had been "partying very hard" months prior to her treatment and had issues with "drugs and alcohol use." "With fame came a partying lifestyle," said the insider, who also made claims that the Texas native had experimented with marijuana, the prescribed sleep aid Ambien, and the anxiety medication Xanax.

While Gomez has yet to explain her reason for attending rehab, some citing "exhaustion" as the cause, another source is claiming that her desire to separate herself from the Hollywood lifestyle was her driving force behind voluntarily receiving treatment. "She was exhausted. Selena was smart enough to understand that she needed to take control of her life," said the source, adding, "It's just got to the point where she needed to get out of Los Angeles and get away from 'the scene' and the pressures of Hollywood, to also get away from those who had, admittedly, become a bad influence on her."

In December, Gomez announced she was canceling her tour in Australia just weeks before receiving treatment, the singer revealing in a statement that the cancellation was due to needed to "spent some time" on bettering herself. "After many years of putting my work first, I need to spend more time on myself in order to be the best person I can be," said Gomez.
