It looks like Paris Hilton is intending to get steamy under the mistletoe this Christmas - by treating someone to a glimpse of her saucy underwear.

The socialite made a trip to the Trashy Lingerie store in Los Angeles where she browsed the rails for sexy santa-themed outfits.

The Simple Life star - who is newly-single after spliting from boyfriend Benji Madden last month - got into the holiday spirit by dressing in a green tracksuit and a top that read 'Santa Baby.'

And this is not the first time Paris has stocked up on trashy fancy dress outfits - the star has hit the members-only underwear shop before to film scenes of her reality show My New BFF.

But who will be seeing Paris' undies this winter?
