On "Practice," set at a posh Los Angeles private medical practice, Strickland will play Charlotte, a doctor and hospital administrator.

On "Grey's," Leigh plays Lexie Grey, the half sister of Meredith (Ellen Pompeo) who comes to Seattle Grace as a new intern. Leigh originated the character in a brief guest appearance at the end of "Grey's" Season 3 finale.

Vandervoort joins another new cast addition, Michael Cassidy, who will recur as the editor of Daily Planet.

Katie Cassidy's character Ruby will make her first appearance on "Supernatural's" third-season premiere. She is a fellow demon hunter whom Sam Winchester (Jared Padalecki) and Dean Winchester (Jensen Ackles) initially meet when they begin searching for the masses of demons who escaped from hell in the second-season finale.

Vandervoort is repped by Noble Caplan Abrams in Toronto and Anthem Entertainment.

Michael Cassidy, whose series credits include "The O.C." and "Hidden Palms," is repped by Gersh, Larry Taube of Principal Entertainment and Vic Ramos Management.
