The Cosby Show's Geoffrey Owens paid tribute to his late costar Malcolm-Jamal Warner following his death at age 54. "This tragedy has almost left me speechless," Owens, 64, told Us Weekly in a statement on Tuesday, July 22. "Malcolm was a lovely man, a sweet and sensitive soul. I respected him for many reasons, including the fact that he genuinely loved the act of creation. He had the mind of an actor and the heart of a musician." Owens noted that Warner had supported him in his own artistic endeavors as well. "He was generous too," the actor said.
