Leighton Meester made an appearance on Young Hollywood Studio recently to promote her new movie, “The Roommate.”

Leighton opted for a super casual laid-back look wearing a black tank top paired with a Carven Spring 2011 high-waisted knot detailed skirt.

I’m sure many of you are thankful she didn’t wear the same top as the model for her TV interview.

Leighton accessorized with Cathy Waterman earrings and a Bvlgari ring.
