The Stars of 'Hitch'

Listen up, would-be Romeos—Ms. Mendes has some love advice of her own: Please don't chew with your mouth open! And don't even think about wooing Eva if you can't handle your liquor—she hates it when a date can't drink more than a few sips without getting woozy. "Oh man," Will jokes, "That's me. She's saying all my stuff."

But if you're Will Smith, maybe you can get away with a thing or two. When he tells Oprah about a wild female fan who propositioned him, whispering the words "Anytime…Anywhere…Anything," Eva doesn't lose a beat: "I didn't say it like that!"

Will shares some more of his dating tips!
