We thought we knew just how low The Hills' reigning king and queen of mean Spencer Pratt and Heidi Montag would go just to garner the slightest bit of attention from the press. Given their history of stunt proposals, staged “paparazzi” shoots, and plastic surgery adventures, the evil duo has proven their weight in gold-digging PR wizardry. But their latest alleged stunt planned for the “reality show”’s upcoming season is creepy enough to inspire the next Law & Order: SVU plotline: "Rumor has it that Heidi Montag and Spencer Pratt have decided to fake a pregnancy for the 4th season." Sadder still? It sounds like they’ve convinced MTV producers — and the wardrobe department — to play along with the lie as old as time...

As the gossip blog I'm Not Obsessed hears, Spencer and Heidi's devised plan will go unacknowledged by MTV, and they've already decided to fall back on the old "No Comment" routine should they be asked about the story. But how will it begin? "Heidi is going to wear loose clothing and possibly some padding to give the illusion that she is several months along." Padding? As in, a prosthetic bump? Last we heard those Oscar-baiting props don't come cheap. Then again, it costs a lot of money to look as cheap as Heidi and Spencer already do, to borrow Stern-suing Dolly Parton's so-true mantra.
