John Mayer looks like he has a new muse to write songs about: Cameron Diaz. The goodlooking pair were spotted at Indochine restaurant in New York City on Tuesday night, ordering cocktails and "lingering over dessert," an eyewitness tells the New York Post. "They were very playful and cozy." And a friend of Cameron's also tells the Post that the two "met years ago at a concert [but] their relationship is just getting started." No telling if this new relationship will inspire John to write another hit like "Your Body Is a Wonderland" (which is supposedly about his ex, Jennifer Love Hewitt).
