Kill Bill assassin Uma Thurman proves that she's a killer on and off the screen at Paris Fashion Week. Thurman, 40, attended the Louis Vuitton presentation Wednesday with her hair pulled back in a sleek 'do and topping her ensemble off with the perfect accessory: a sexy red lip. The hot mother of two also made a stunning entrance at Karl Lagerfeld's Chanel show, where she wore the brand's signature fabric, tweed.
