Kate Moss pAArties It Up With Stella McCartney

Kate Moss has seen better days.

The fashionable model was spotted leaving The Groucho Club in London Tuesday night.

Moss was there to celebrate Stella McCartney’s 40th birthday party.

And by the looks of things, Kate had a good time — a really good time — as she needed help being escorted to the car.

On the plus side, we are loving her strapless, jumpsuit with the oversized bow!
