Kim Kardashian (and Katy Perry) Take Paris By Storm This Week

On Tuesday, Kim Kardashian stepped out in a headline-making plunging black dress in Paris for a screening of the documentary of “Mademoiselle C” about former Vogue editor-in-chef Carine Roitfeld’s move to New York to launch her own magazine.

The Paris trip has marked Kardashian’s big reentry into the public eye after the birth of her and Kanye’s baby North West. She attended the event in the revealing get-up alongside Givenchy creative director Riccardo Tisci. The 32-year-old reality star, who initially became famous for her body and one particular "home video" with rapper Ray J, has slimmed down considerably after the baby, following months of body-obsessed tabloid reporting.

Katy Perry was also at the event. "Mademoiselle C," directed by Fabien Constant, is getting a limited U.S. release.
