Watch: Kristen Stewart Dressed Down in New Chanel Ad

Prepare for some important KStew news. Designer Karl Lagerfield has released a new ad for Chanel's Paris in Rome collection, and the former Twilight and The Runaways actress is the star.

Stewart spends the 30-second spot sexy-walking around a Paris apartment in black lace tights, a fitted black dress, big hoop earrings, and a tulle jacket. She takes some of these things off in the video. "I'll Take Care of You," covered by '70s poet Gil Scott-Heron, plays in the background.

Oh yeah, and a Chanel calfskin bag is somewhere in there. We may have been distracted.
