Kate Upton Goes as Kate Upton for Halloween

That chick that dressed up as Kate Upton at the Pink Taco Halloween party on Sunday? That was Kate Upton.

From the New York Post:

Kate Upton managed to go incognito at Sunday's Halloween Costume Contest at Pink Taco on Sunset Boulevard -- by dressing casually and covering up her famous body. Looking low-key in jeans, a T-shirt and a trucker hat, a source tells us, the busty Sports Illustrated Swimsuit model fooled partygoers who mistook her for a look-alike. "Someone finally realized it was the real Kate," says the spy.
