Paris Hilton goes from chav to prom queen as she shows off five outfits in 24 hours

Paris Hilton is nothing if not versatile.

The heiress hit the set of David Letterman yesterday looking like a polished prom queen in a stylish citrus dress.

The night before, she was spotted leaving LA airport dressed as a tracksuit-clad chav.

The 26-year-old showed off a number of other outfits while making her way around New York, taking her total costume changes to five in a mere 24 hours.

She was in the Big Apple to continue her promotional duties for her new movie The Hottie and the Nottie, which is slated for release later this year.

In the film, Paris stars as the object of affection for Nate, played by Joel Moore, who's had a crush on her since primary school.

To win her over, he must first find a boyfriend for her less attractive friend.

It's has been a hectic week for the star - on Monday she party-hopped her way across LA, stopping in at lesbian bar Falcon on Sunset Boulevard on her way around town.
