Holly Madison

For those of you who don't follow E! reality shows, Holly Madison is a former Playboy model who bravely served as one of Hugh Hefner's official girlfriends from 2001-2008, starred in the series The Girls Next Door, did a stint on Dancing With the Stars earlier this year, and now appears in the Planet Hollywood burlesque extravaganza Peepshow. She's also a UFC fan who Dana White once described as "one of the sweetest, most genuine people you could ever meet." Most importantly, she's an incredibly hot chick who will be adding star power and some much-needed blondeness to the Octagon Girl pit at UFC 100. As Holly posted recently on Twitter (props to MMA Mania for the tip):

Keep in mind that the UFC is still going to pluck one lucky lady out of obscurity during their Octagon Girl Search this Saturday, but we dig the "celebrity guest ring girl" angle. Could Mandy Moore be next? More pics of Ms. Madison are after the jump. Check out more of her work at HollyMadison.com, and be her eBuddy at MySpace.com/hollyewok.
