The other day we saw Amy Smart topless in nipple tape on the set of Crank 2, and today she's back, and she's kicking ass. And speaking of kicking ass, Amy Smart's ass is pretty kick-ass itself. You know what else is kick-ass? This Amy Smart nipple slip. I guess with all that ass kicking going on, they forgot the nipple tape this time.
Check out more of Amy Smart kicking ass after the jump. And yes, that is Corey Haim. With a mullet.
