MTV has the story.
"It was my birthday, so we was poppin' bottles," he continued. "We was bottle-poppin' major. Pain was talking to this chick and this big football-player-looking dude came up. He was big as hell. ... The dude grabbed her arm and she was like, 'I'm not leaving,' and [moves] away from the dude. ... The next thing you know, the dude started talking sh-- to Pain. The dude poured his wine out and ... I looked back at my security [guard], gave him my chain. He put it in my case and handed it to Rico. The dude hit T-Pain's partner in the head with a glass in his hand."
