This tidbit is FemaleFirst-penned, so take it with a Hummer full of salt, but Posh Spice and equally groomed hubby David Beckham are reportedly having sex standing up, because they heard that's a surefire way to conceive a girl. In related news, the Beckhams also say that you can't get pregnant when you do it doggy-style, and if you use tampons, you're like totally not a virgin anymore.

Hahahahahaha. HAHAHAHAHAHAHA! Functionally retarded to begin with, all that exposure to Mystic Tan fumes has rendered Posh Spice's brain on par with that of deep sea comb jelly. The Beckhams have three boy babies that they apparently regard as failed experiments, since they're dying for a girl. So dying, in fact, that they've taken to following tips from a dubious book. A source blabs:

"David is really keen for Victoria to have another baby. But he wants a girl. And when David wants something, he gets pretty obsessed. He's found out through talking to people that you have more chance of conceiving a girl if you do things like have sex standing up on certain days of the month. He's even checked out this website that claims to guarantee a couple having a baby girl, and there's a book called 'Determining The Sex Of Your Baby', which is all about whether you can plan to have a boy or a girl."

God, why don't they just buy one, like Rosie O'Donnell or Meg Ryan? At any rate, Posh has had three cesareans so far, and with each C-section, the risk of complications increases, so she's really putting her health on the line trying to pop out a girlchild for her buffed and waxed spouse. Not to mention the fact that she weighs 83 pounds and the only nourishment the fetus will get is Balance bars, champale, and fibers from the leather strop Posh gnaws on when she feels the urge to eat. But hey, that'll just teach the baby girl the fine art of weight control. Nobody likes a fatty.
