Kelly Osbourne is in rehab.

The 24-year-old star has checked in to a treatment facility just outside Los Angeles, but no further details have been released.

Her mother Sharon confirmed: "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."

Sharon refused to specify what Kelly - who has checked into rehab twice before for an addiction to painkillers - is being treated for, but the star is expected to stay in the facility for at least 30 days.

An emotional Sharon added to Radar Online: "Kelly will tell you herself when she gets out. We just pray that everything's going to be OK.

"This is one of the absolute worst things that a parent can face, for their child to go through rehab. However, we are all very glad Kelly's doing it."

Although details of Kelly's treatment are yet to be revealed, America's Star magazine has reported she checked into Hazelden alcohol and drug rehabilitation centre in Newberg, Oregon, on January 21.

A source is quoted as saying: "Kelly realised she had a problem and made the decision to go back for treatment. Her life was spiralling out of control and she needed help."
