Dylan Walsh is remembering his “Nip/Tuck” co-star. After Julian McMahon died on Wednesday at the age of 56 following a private battle with cancer, the “Unforgettable” alum, 61, shared a touching message for the late actor.

He played the half-human, half-demon Cole Turner in the WB supernatural series “Charmed” and a self-destructive playboy in the FX series “Nip/Tuck.”

McMahon was known for portraying villain Doctor Doom in 2005’s Fantastic Four and the 2007’s sequel, Fantastic Four: Rise of the Silver Surfer. He also played Christian Troy in Ryan Murphy’s Nip/Tuck and Cole Turner in Charmed. His more recent credits were in The Residence and The Surfer.
