Vegasis betting big on family drama.

Winter Preview: Get scoop on your favorite returning shows

The freshman CBS drama has cast The O.C.and Nikitastar Melinda Clarke to play the mother of Sarah Jones' Mia Rizzo, TVGuide.com has learned exclusively. Clarke will play Lena, a charismatic, shrewd, strong woman who is attracted to even stronger men. Although Mia's father (Michael Wiseman) insisted that Lena died when Mia was a baby, she's alive and well, having been forbidden to see or contact her daughter. Naturally, her arrival at the Savoy will ruffle a few feathers.Speaking of ruffled feathers, as we first reported, Lena catches the eye — and a whole lot more! — of Vincent Savino (Michael Chiklis) before he learns her true identity.
