The Girls Next Door 10 Years Later: From the Playboy Mansion Limelight to Bitter Bunny FightsA decade has passed since we first met Holly Madison, Bridget Marquardt and Kendra Wilkinson on the E! reality show

WHERE PARTYING IS SERIOUS BUSINESS

Ain't no party like a Playboy Mansion party! The Girls Next Door – starring Hugh Hefner and his girlfriends Holly Madison, Bridget Marquardt and Kendra Wilkinson – gave us a sneak peek at all the glamorous Bunny bashes we'd only heard about before the show first aired – and (surprise!) they were even more extravagant and star-studded than we thought. Notable fêtes included the annual Midsummer Night's Dream affair, Holly's Marie Antoinette-themed birthday party and the scantily costumed Halloween shindig (2006 party pictured left).
