{blackbabes} Swizz Beatz throws VIP birthday bash for Alicia Keys

Swizz Beatz threw a private 33rd birthday bash for wife Alicia Keys after the Grammys.

Spies at the Hollywood Hills mansion party said there were just 75 guests — who had to all check their smartphones so that no social media pics could be posted.

Rapper Nas performed "Hate Me Now" with Sean "Diddy" Combs, and then pulled Keys up onstage to sing Lauryn Hill's part of his hit "If I Ruled the World." Stevie Wonder also performed a set of songs including "My Cherie Amour."

DJ Cassidy spun tunes for guests including music moguls Steve Stoute, Andre Harrell and Russell Simmons as well as rapper Busta Rhymes.
