John Tucker Must Die (2006)

Three ex-girlfriends of a serial cheater hatch a plan: to make him fall in love with a fourth girl only to see him heartbroken.
In the 43rd minute Brittany Snow wears a blue robe and lowers it to show a black bra. A girl sets up a camera on one side of her breasts. In the forty-eighth minute Brittany Snow and Sophia Bush kiss on the seats of a car, in an unfortunately very brief scene. In the sixty-fifth minute Brittany comes out of the bathroom wearing a black robe, then opens it in front of a group of girls lying on a bed and shows herself in sexy red lingerie. The girl sits at a computer and talks on cam with a guy. She shows the sexy lingerie to him as well.
