It’s only been three weeks since former “Girls Next Door” star Holly Madison gave birth, but she’s already close to that pre-pregnancy body that once graced the pages of Playboy! Hitting up the red carpet on Friday night for the “One Night for One Drop” World Water Day event in Las Vegas, Holly showed off the weight she’s already shed in this short time and she looks amazing. She and Lola Monroe must be on the same plan! LOL! Check out Holly’s weightloss in the gallery.
