Kelly Osbourne has checked herself back into a drug treatment centre, only a year after completing a successful stint in rehab.

The 20-year-old daughter of Ozzy and Sharon Osbourne, checked into Pasadena, California's Las Encinas hospital on Thursday (02JUN05), according to American magazine US WEEKLY.

A friend tells the publication, "She's going to be in for a couple of weeks. She's slipped into some of her old problems and is not doing so well. Everyone is supporting her."

Another source adds, "Friends are concerned, but know that she's strong and that she's pulled through before and will this time as well."

In April of 2004 Osbourne spent time at Promises, a treatment centre in Malibu, California, for her well documented addiction to prescription painkillers.

Her brother JACK and father Ozzy have both battled drug addiction.

A representative says, "Kelly is in a facility dealing with some personal issues. She'll be back in a few weeks."
