The man knows how to make an entrance: Kanye West pulled up to his 30th Birthday bash at Louis Vuitton in New York City yesterday in a red Lamborghini. Inside the star-studded bash, rappers and rockers all came out in full force to wish the dapper, tuxedo-clad hip-hop star a happy birthday. Mariah Carey, Usher, Jay-Z, Sean "Diddy" Combs, Pharrell Williams, Travis Barker, and the guys from Fall Out Boy - including Pete Wentz, with girlfriend Ashlee Simpson in tow - all whooped it up in honor of Kanye. The evening's real VIPs? Kanye's mom and dad, who were also in attendance.
