One day after news broke that The Cosby Show's Malcolm-Jamal Warner tragically drowned while on vacation in Costa Rica, his TV wife is paying her respects. In a heartwrenching Instagram post on Monday, Tracee Ellis Ross paid tribute to her Reed Between the Lines co-star: "I love you, Malcolm. First I met you as Theo with the rest of the world then you were my first TV husband. My heart is so so sad.
