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.

Costume change: while in New York, Paris hit the Fifth Avenue in a casual white ensemble, then frocked up in a navy and gold dress for an appearance on TRL, before changing into a grey smock to attend a launch party for the new Blackberry

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.
