'The Ugly Truth': Katherine Heigl, Gerard Butler gag reel

"The Ugly Truth's" Katherine Heigl and Gerard Butler had chemistry off camera as well as on.

You can check out the co-stars put the comedy in romantic comedy with this gag reel for "The Ugly Truth" DVD.

In the film, Heigl plays Abby Richter, a rather uptight and romantically challenged morning show producer, who disagrees with Mike Chadway, the rather chauvinistic host of a popular segment called The Ugly Truth.

He tries to prove his theories on relationships to her and help her find love, but instead, well, you know. It's that romantic comedy formula at work again.

Watch as the stars flub lines and goof off:
