Paris Hilton is back from her lovely holiday in St Tropez and back to... er... whatever it is she does in LA.Judging from this picture she's either off to an audition for Taylor Momsen's band The Pretty Reckless, or to the set of Pretty Woman 2.

The socialite walked around wearing a lace top over a black bra, with black jeans and a black leather jacket, for if she gets too cold in her outfit of mostly nothing. Also we're sure it's way too hot in LA to be dressed like that.
