The music industries smoothest rapper cut it up on the dance floor as he partied it up in style for his 30th birthday bash! Big time guests, Jay-Z, Mariah Carey, Rihanna, Fall Out Boy all joined the cocky lyricist on the dance floor at the Louis Vuitton store in NY! The night was filled with bathing suit clad dancers (Luis Vuitton suits of course!), glasses of overflowing Dom Pérignon (Fxxx Cris!) and to top it off, the b-day boy himself took to the stage with Pharrell Williams, the Clipse and John Legend...do you really think Kanye could resist the stage even on his own b-day! The party didn’t end at the Louis store…the afterparty moved to Tenjune where R&B sensation Usher and recently single Gabrielle Union joined them…Happy Birthday Kanye!
