Kate Turns Chav

Kate Moss goes chavLord above - has fashion guru Kate Moss gone chav on us?

Fret not, it's all for charity.

The supermodel kindly left her cool clothes at home to don a tracksuit top, leggings and a hair scrunchie (remember them?).

And all so she could play Vicky Pollard's twin sister in a charity gala performance of Little Britain.

And typically, she still managed to look good.

Pushing a buggy, she waltzed on stage to cheers from the audience at London's Hammersmith Apollo to take part in the Matt Lucas and David Walliams show.

Matt, who plays queen chav Vicky, told the crowd how Kate was the pretty one of the family.

"I'm anybody's for a packet of Quavers."

And as she left the stage, Vicky yelled: "Kate, lose some weight, you fat bitch."

Hilarious.

But Kate wasn't the only celeb to join in the special LB show.

Russell Brand played a plumber working for David's transvestite character Emily Howard and Jeremy Edwards got stripped by Des Kay and poor Chris Moyles found himself on Marjorie Dawes' scales at Fat Fighters.
