The Vagina Mysteries

The title of the hit movie "Knocked Up" suggests that Katherine Heigl's character is going to give birth, and boy does she ever! If you haven't yet seen the comedy, sorry to spoil it for ya, but there are multiple shots of a baby popping out ... with the camera right there between mom's legs. Or was it?

TMZ put its detective cap on to find out how "Knocked Up" writer/director Judd Apatow created this graphic scene and still managed to get an R Rating. We spoke with Larry of Honey's Place (an adult novelty distributor often called the "Costco of the porn industry") who believes the scene could have been created with special effects. Larry told us "We have vaginas in our warehouse. (Holy moly!) Manufacturers like Doc Johnson take a real porn star and make a latex mold of the body -- and they are pretty lifelike." Gee. Larry doesn't pussyfoot around.

Linda Teglovic, agent/owner of Body Parts Models says it's a tough job. "I would have a hard time finding a girl to do that," adding she has never seen a request for a "vagina double" on any breakdowns (casting call lists) that she's seen. But then again, anything's possible.

The New York Times Magazine reported in May that "The Devil Wears Prada" star Anne Hathaway was originally cast in "Knocked Up," but pulled out because she had problems with the vagina. Apatow told the Times "Hathaway dropped out of the film because she didn't want to allow us to use real footage of a woman giving birth to create the illusion that she is giving birth."

The MPAA wouldn't return our calls and Apatow was unreachable. Our best guess, culled from these snatches of information, is that "Knocked Up" used a stunt vagina.
