One heckler caught the attention of Lil’ Wayne, and the end result wasn’t pretty. Over the weekend, the Young Money rapper was scheduled to perform a concert at Revolution Live in Fort Lauderdale, Florida on Saturday night. Fans became restless after Weezy didn’t appear on stage until around 3:30 a.m. according to TMZ. One fan in the crowd took it upon himself to vent publicly, aiming his iPhone to the stage, where people in clear view could see the scrolling “Shut the f*** up and put on Weezy” message on the cell phone’s screen.

When Lil’ Wayne showed up, the screen was then changed to simply say “F*** Weezy.” Not amused by the heckler’s actions, Lil’ Wayne appeared to point out the culprit to one of his security guards, who then seeked out the unknown man in the crowd and then went on to knock him out cold. In video obtained by TMZ, the security guard rushes back on stage after throwing heavy blows to the heckler, who was carried out by clubs security.
