Deb Grimmel helps Nelly celebrate his birthday at Marquee Nightclub.

Nelly kicked off his birthday celebration last night in the Boombox Room at Marquee Nightclub at the Cosmopolitan of Las Vegas. He arrived late, keeping it low key with his hoodie up, but still managed to pose for photos with fans. Later in the evening he was surprised by cupcakes and shared with his party.

Next to Nelly’s table was Red Sox outfielder Carl Crawford’s party. The two became friends fast. Crawford treated Nelly to a magnum bottle of Ace of Spades Rose as a birthday gift.

Nelly stayed late and kept DJ Fred Matters busy with requests all night including hits from Jay-Z and Kanye, old NWA jams and Too Short’s Blow the Whistle. The party continues with a Saturday night stop at Tao Nightclub at the Venetian.
