In a sexy lace-up Altuzarra dress and strappy white Givenchy heels, Williams bared a hint of cleavage as she promoted her new movie alongside co-star Luke Kirby. In the movie, Williams and Seth Rogen play a married couple whose relationship is tested by an attractive new neighbor. (Kirby, obvi -- look at him!) Boyfriend Jason Segel, unfortunately, was nowhere in sight.
Speaking of attractive folks in Hollywood... Michelle's not looking too bad herself.
