What is it about MTV awards ceremonies that brings out so many female celebrities' inner hooker? Normally demurely dressed stars like good girl Anne Hathaway and Charlize Theron both showed up on the red carpet looking like a dominatrix-for-hire and a Heidi Fleiss escort circa 1990, respectively. Megan Fox stepped outside her rep as being a poor girl's Angelina Jolie by attempting to dress like a cupcake, but the frilly underskirt just said Little Pink Ride Your Hood, and The Hills resident scandalista Audrina Patridge donned a skin-tight, midnight blue satin one-strap number paired with ironed black hair that looked eerily like what we suspect Marilyn Manson wears in drag. So why pick last night to debut their diaper-length hemlines and S&M costumes? Look no further than a closer peek of Lindsay Lohan's totally unintentional panty-flash for answers, and the rest of these ladies of the night after the jump:

As Gwyneth proved quite effectively during her Iron Man press tour by wearing kinky boots and transparent mini-dresses, slipping into a costume designed for tightening trousers goes a long way towards catching the attention of not only the horny teen boy population, but also the millenial MTV viewers. Not to mention the sex-obsessed network's not-so-subliminal message that bisexual MySpace stars are worthy of icon status, that you can't really have a good time unless you're stripping down to nothing in hot tubs with your Real World roommates, and that what people REALLY want to see are endless barrages of Top 20 Sexiest Star/Hottest Bods/Sluttiest Sluts countdowns. So who can really blame girls like Charlize and Anne for following the crowd?
