Kelly Osbourne bleach blonde Beverly Hills

Whoa, this is nutty. Let's break it down.

Kelly Osbourne has already ranted on Twitter about her ex fiance Luke Worrall cheating on her... but now the apparent "other woman" in question, Elle, tells the Sunday Mirror that she was originally born a man.

"I was open with Luke that I was born a boy. He didn't mind - in fact it turned him on more. He always insisted to me he was single and I had no idea he was engaged to Kelly Osbourne," claims the 21-year-old Elle.

But now Elle realizes "it was all lies. At the same time as he was professing his love to me, he was doing the same to Kelly."

Elle explains that she met Luke at a New York nightclub over a year ago. She has undergone hormone therapy for three years ahead of her sex change - she also has breast implants.

Damn, could this really be true? Poor Kel!
