She's the star of the Battlestar Galactica TV series, so she has the power to do the classy Playboy pictures. She has done lots of other acting too.
I just saw a lovely two-page spread of the '94 Versace runway show in a fashion book, where she walked with all the classical supermodels.
She won Ford Supermodel of the World at 18, in 1992. From the Alberta wheat fields right to a very successful 10-year modeling career, then acting.
