She certainly knows how to throw a party!

Over the weekend Fergie hosted a baby shower at the SLS Hotel in West Hollywood, and the expectant starlet tweeted the pics above and wrote, "It's gayby shower day! He's trying to talk! Thank u @pattersean, @Dsquared2 & @andylecompte 4 the best #GaybyShower ever. #ifeelloved"

Kelly Osbourne, Adam Lambert, Molly Sims and Gabriel Aubry were among those in attendance and the theme of the bash was black, white and blue. Burlesque drag performers gave guests quite a show, and according to People, pals drank Fergie-inspired cocktails through black and white striped and polka-dot straws with musical notes and flags. She really planned this thing out!
