Chris Noth stripped down to take a shirtless swim in Miami yesterday before he hit the Audi party with Kellan Lutz. We'll be seeing Chris all buttoned up as Mr. Big for Sex and the City 2, but these days he spends his time on other small screen projects like Law and Order and The Good Wife. It's been a few years since Chris's heartthrob heyday, but tell us what you think of him at the beach — sexy or not?
