Former reality television star, Kelly Osbourne, has checked into rehab.

The daughter of rock legend Ozzy Osbourne and America's Got Talent judge Sharon Osbourne entered an unnamed center in Los Angeles for 30 days, according to People.

"Kelly Osbourne has voluntarily entered a medical facility to address some personal issues," her London-based rep said. "Her family stands by and supports her."

On Thursday, the 24-year-old's mother Sharon told RadarOnline, "Yeah, Kelly's in rehab. What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it."

Kelly Osbourne previously entered a treatment facility for an addiction to painkillers nearly five years ago while the family's reality show, The Osbournes, was still on air.
