KEY POINTS:
Radio presenter Kelly Osbourne has checked into rehab in the US for the third time, her mother Sharon confirmed.
The 24-year-old, who co-presents Radio 1's Sunday Surgery, was treated for addiction to painkillers in 2004 and was re-admitted a year later.
Sharon Osbourne said: "Yeah, Kelly's in rehab. The family is all standing behind her. She knew that it was the right thing to do at this point and we're proud that she did it."
Her UK publicist said Kelly had voluntarily entered a medical facility to address some personal issues.
Kelly Osbourne rocketed to fame off the back of MTV reality show The Osbournes, which focused in the family life of rock legend Ozzy and wife/manager Sharon.
After a short-lived pop career, she carved out a career as a presenter with Radio 1 since 2007.
