Singer reveals a relative has the virus

Kelly Osbourne fought back the tears last night as she revealed a member of her family is HIV positive.

The 22-year-old made the shock announcement at the fundraiser for HIV charity Body & Soul.

Introducing the Scissor Sisters on stage, she said the cause was special to her because a member of her family had been diagnosed with the illness.

The daughter of Ozzy and Sharon apparently then sobbed before leaving the stage at Koko in Camden, north London.

It is not clear who the member of the family is, and representatives for Kelly today declined to comment.
