Although much has been made of her costar Robert Pattinson's luscious locks, New Moon star Kristen Stewart dreams of caressing another man's hair: Conan O'Brien's!

The 19 year-old actress acted on her desires during her Monday appearance on NBC's Late Night with Conan O'Brien.

Stewart admitted that she was "jealous" that her friend Nikki Reed (Rosalie in the Twilight films) was "bold enough" to run her fingers through O'Brien's red mane during a 2008 Late Night appearance.

"Can, can I do it?" she asks O'Brien, fidgeting in her seat.

"It's really not that big a deal," O'Brien says, leaning his head forward, and growling when Stewart gives it a stroke.

Stewart then introduces an edgy New Moon clip starring her and the "wolf pack" -- husky, bare-chested hunks who morph into wolves.
