Selena Gomez underwent a stint in rehab last month, it has just been revealed.
Selena is said to have spent two weeks there in January to be treated for "exhaustion".
The 21-year-old cancelled her Australian tour at the end of December, with reports citing Lupus as the reason. This, however, was never confirmed and this was her statement at the time.
The revelation comes less than two weeks after her ex Bieber was arrested for DUI and drag racing in Miami.
BuzzFeed will update with more information as soon as we get it...
