Ah, the life of being one of the world's most famous celebrity rappers. At the Playstation 3 launch party in L.A. this week, Diddy got funky with a star-studded crowd, including Paris Hilton, Nicole Richie, Stacy Keibler, Katharine McPhee, Xzibit, Nick Cannon, Christina Milian, A.J. McLean, members of Lifehouse and more.

But the rapper, who remarked he hadn't played an L.A. show in probably 10 years and showed off his vocal prowess on 'Last Night' (from his new 'Press Play' release), also reminded partygoers of where he came from, raising a toast to his fallen friend, Notorious B.I.G.

Watch Diddy's Sessions performance.
