Pop singer/reality TV star Kelly Osbourne is being stalked by an obsessive transvestite fan.

The 21-year-old daughter of Black Sabbath rocker Ozzy has hired minders to keep the male devotee away from her at public events.

She says, "Honestly, I have got security men who have to really keep an eye out for this one fan.

"I can't stand it when he shows up although it's hilarious as he loves wearing women's clothes.

"At first I didn't realise he was anything to worry about and I am sure he is harmless.

"But you have to be careful in this industry so I'm not taking any chances."
