On Nip/Tuck, Julian McMahon plays Dr. Christian Troy, the business partner, best friend and confidante of Dr. Sean McNamara. Handsome, charming and often promiscuous, Christian has no sexual inhibitions, as he enjoys the perks that his lucrative career offers. Last season, Christian became engaged to Michelle (guest star Sanaa Lathan), only to end the engagement when he learned of her dark, criminal past. This season, he embraces the Los Angeles nightlife and attempts to keep a betrayal from Sean as he resides in Malibu with his 5-year-old adopted son. Christian's near-constant need for love and attention takes him on a sexual journey that surprises him.

Having been nominated for a 2005 Golden Globe Award and a 2006 Saturn Award for his work on Nip/Tuck, McMahon recently appeared on the big screen in the hit summer sequel Fantastic Four: Rise of the Silver Surfer.
