Rod Stewart: "It's always been a thorn in my side when they try to make you look 16. I'm very proud of my well-earned wrinkles, so show 'em."
CNN: You're 64.
Stewart: "Yes, it's great, isn't it! (Cracks up) Yes, 64 now."
CNN: You don't look 64 at all, and you don't act a day over 17.
Stewart: "Oh, behave yourself."
