Kate Moss is one of the faces - and bodies - of the size zero craze that is currently infecting Hollywood.
The supermodel has been famous for her waif-like physique since she burst on to the modeling circuit as Calvin Klein's muse.
Now, according to reports, Kate and her London A-list friends are obsessed with looking as thin as possible and have coined a new phrase to compliment each other.
The Mail newspaper in England claims that Kate, Sadie Frost and other skinny stars are calling each other "rexy" when agreeing with their body.
A source explained, "'Rexy' is a word that Kate and her friends have made up. It is a hybrid of the words anorexic and sexy. It is used by Kate, Sadie Frost and other members of that A-list crowd to make a statement to each other that they are looking good. It's not an insult, it's a compliment."
Newly single Kate, who has a four-year-old daughter Lila Grace, has previously claimed to be naturally thin. She once said, "It is flattering that other women want to look like me. There are lots of people I'd like to look like, too, but I'm fed up with all the scandal about my weight. I'm just skinny, that's all."
Kate has dropped pounds since splitting with her drug addict boyfriend Pete Doherty.
