When you spend your days playing a teen alien living in Roswell, N. Mex., you have to expect the unexpected. "Once, I was filming this dream sequence with Jason Behr, and we were both covered in green makeup and wearing these Darth Maul contacts," says 21-year-old Katherine. "It's fun being on a show like this where you have no idea what's going to happen each week." To give Katherine an out-of-this-world look, Nick smoothed a silvery shadow all over her top lids (for example, Cover Girl CG Smoothers Gel EyeColor in Midnight Metal). Next, he applied a black shadow in the outer corner of the eyes, blended it upward and lined the eye with black pencil (try Tony & Tina Crayon Eye Pencil in Black). He used a plum blush on her cheeks (we like Lancome Blush Subtil in Aubergine) and a metallic gloss on her lips (try Trucco Divinyls Lip Gloss in CyberLiscious). Earthlings, take note!
