The church is booked, friends and family are invited, and yet the wedding is canceled. What could make a girl go to such desperate lengths? For Haylie Hocking, it was finding out her soon-to-be husband is a porn star.

Apparently, being huge in the pants and always doing it in camera-friendly positions weren't clues enough for Hocking, 27, who only found out after her friend saw her fiancee with a woman in a porn movie while cruising the Web for a bachelorette party stripper. It was a deal-breaker.

In honor of the venerable Liz Lemon, we came up with some deal-breakers and non-deal-breakers of our own after the jump.

Deal-Breakers:

Whispering "I killed your dog" during an intimate moment.

His secret obsession with Miley Cyrus.

Learning he's pretending you're an angry horse during sex.

Non-Deal-Breakers:

Eats all the peanut butter in his sleep ... every night.

Refuses to put the seat down.

Penchant for Root Beer schnapps.

Tell us! Some things (like cheating, abuse or addiction) would shut down even the truest love, but what about a curable STD, an embarrassing fetish or a long-done-with shady past? What are your deal-breakers?
