Grammy Award-winning rapper and actor Cornell Haynes, Jr. aka Nelly was all smiles last night as he celebrated his 37th birthday with Atlanta friends & family.

In what doubled as an after party for the 2011 Soul Train awards, which taped in Atlanta earlier that evening, Nelly partied the night away at Alex Gidewon’s Vanquish night club.

Celebrities in attendance included: T.I. and his wife Tiny, Miguel, CeeLo Green and Goodie Mob, Lance Gross, Keshia Knight Pulliam, Raheem Davaughn, Jazze Phae, BET and Centric Executives, Stephen Hill (BET) and Kenard Gibbs (CEO, Soul Train), Nivea and more…
