The 49-year-old actress and comedian revealed to Oprah she started to watch her weight, but instead of avoiding certain foods or sweets, she opted for alternatives within her daily eating habits: "I take a banana and strawberry, and put frozen cool whip on it with a chocolate drizzle, and tell myself it’s a banana split,” she said.
