Kanye West's star-studded birthday bash hit a glitch when party organizers misspelled his name on his birthday cake. As the rapper celebrated at New York's Tenjune nightclub he was presented with a huge cake incorrectly emblazoned with the name "Kayne."

The misspelled treat followed some awkward goodbyes at the Louis Vuitton mansion, where his evening began.

Sources claim to have overheard P. Diddy yelling, "I can't believe you don't call me back, Jay. Don't play me like that," at an apologetic Jay-Z.

At the Louis Vuitton mansion Kanye enjoyed live performances from John Legend, Pharrell Williams and the Shiny Guns.

Other guests who helped celebrate the hip-hop star's landmark birthday included Mariah Carey, Rihanna, Ashlee Simpson and her boyfriend Pete Wentz.

As he began celebrations, Kanye said: "I'm in my 20s as we speak right now, but at midnight, I'll be 30. I'm already 30 in Japan and London and everywhere else."

Tenjune owners Eugene Remm and Mark Birnbaum were also celebrating their birthdays, leading another guest Owen Wilson to reportedly declare he had no idea whose birthday he was attending.

Kanye was joined by more music stars including Fabolous and Usher before officially turning 30 at midnight.
