Brand new music from Nelly produced by Polow Da Don. This is the song that we’ve been hearing about for a while now. The track is called “Party People” and features Fergie. It’s the new single off Nelly’s forthcoming Brass Knuckles, in stores June 24th. Fergie not only sings the hook, she also has a rap verse. Nelly is shooting a video for the song this week in Los Angeles.
