Ozzy Osbourne's daughter KELLY is denying claims she has checked into rehab for the second time.

Us Weekly claims 21-year-old Osbourne checked into rehab on 27 January (06) in a desperate bid to conquer drug and alcohol dependency.

In 2004 the SHUT UP singer was treated for an addition to painkillers.

Osbourne's spokesperson insists, "Kelly is not in rehab."

However, an unnamed source tells the magazine, "Her mom (Sharon Osbourne) staged an intervention."
