Witherspoon's real-life friend Chelsea Handler plays Lauren's best friend and confidant, Trish. However, in real life their roles are reversed, as Witherspoon is the stable married one with kids giving dating advice to the luckless-in-love Handler. To keep the movie's PG-13 rating, McG had to cut a lot of Handler's jokes, most of which were ad-libbed. One of Handler's ideas that did make it into the movie was a little zest added to the love scene in which she and her husband use Cheetos to help them get in the mood. It's been called the “unsexiest sex scene” ever.
