Pitbull told MTV.com the incident happened during the first few minutes of that night’s show when the fan was throwing money up onto the stage, despite repeated warnings asking him to stop.

Says Pitbull:

“I told him, ‘Look, dog, you already got three strikes. Don’t make it rain no more, I’m telling you. I ain’t gonna talk about it no more, I’m just gonna be about it. Don’t do it no more… Boom, left it alone. I started ‘Bojangles,’ then about a minute later, he comes to the other side of the stage and throws money again.”

Pitbull went on to say he had no intention of punching the guy out when he pulled him onstage, and only meant to warn the fan. However, the fan had other ideas and threw more money at Pitbull, this time in the rapper’s face.

According to Pitbull, “When he did that, that’s when natural reaction … natural instinct kicked in.”

Pitbull apologized to the crowd for the interruption, and the show continued after the money-throwing fan was escorted out of the building.
