Kelly Osbourne KOsbourne042308_12_X17.jpg Kelly Osbourne, 23, has checked herself into rehab, according to Radar Online.

Sharon Osbourne confirmed the news to the website and said, "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 added, "This is one of the absolute worst things that a parent can face, for their child to go through rehab. And not once, but twice. However, we are all very glad Kelly's doing it."

Star reports that Kelly will be staying at the Hazelden Alcohol and Drug rehabilitation center in Newberg, Oregon, and an insider tells the mag, "Kelly realized she had a problem and made the decision to go back for treatment. Her life was spiraling out of control and she needed help."

This will be Kelly's third trip to rehab - in 2004, she went to Promises in Malibu for an addiction to prescription painkillers, and in 2005 she checked into the Las Encinas Hospital drug rehabilitation clinic in Pasadena.
