Katherine Heigl's Stunt Snatch

Hey, dummies, that is not Katherine Heigl's naked vagina with a baby head pushing through it in the pivotal birth scene in Knocked Up. Sorry to disappoint, but Ms. Heigl did not spread her legs wide, shove a human infant inside of her poon, position said child's head just so, and allow a camera crew to film the whole rigamarole. Despite her commitment to her craft, that might be taking it a hair too far. TMZ blows the lid off this outrageous conspiracy and attempts to get to the bottom of the front part:

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.

Aside from the fact that most nine months pregnant women we've known (and being sensitive sorts, we like to befriend the heavily child-laden regularly) have more on their mind than being freshly waxed bald like the vadge in the flick, we pretty much figured it was a fake from the beginning, since it looked less human than a Fleshlight. But whatever, we're more intrigued with the idea of a porn industry Costco. Where can we get a card, because we want to push a cart laden with bargain basement double pronged dongs and a 6.5 gallon drum of Astroglide, whistling a happy tune.
