Lil Wayne has slammed the National Basketball Association for banning him from all games.

The rapper took the stage for a concert in Houston, Texas on Sunday night.

He let the insults fly when he grabbed the mic for a show during the association’s highly anticipated All-Star Weekend.

"The NBA banned me from all NBA events - because the Miami Heat told them to ban me,” he told the crowd.

Wayne was barred from attending games for the team in his adopted hometown last week after he supported the Los Angeles Lakers during a match. There were also reports of the rapper making a “gun gesture” at another fan, according to TMZ.

Wayne claims the NBA is backing executives at the Heat and is now blacklisting him.

The hip-hop star isn’t taking kindly to the ban.

“When I say f**k, you say NBA! When I say f**k, you say Miami Heat!" he continued on stage.

Wayne went on to insult the club’s players.

"F**k LeBron. F**k She Wade. F**k Chris Bosh. F**k all y'all,” he said, adding, "I f**ked Chris Bosh wife."

Chris Bosh has yet to publicly respond to the remarks.

Wayne, real name Dwayne Carter, Jr., is no stranger to controversy.

Last week, the 30-year-old star won headlines for controversial lyrics in a newly released remixed version of rapper Future’s single Karate Chop.

The song mentioned civil rights figure Emmett Till, a black teenager famously murdered for whistling at a white woman in 1955.

Wayne’s rhyme: “beat the p**sy up like Emmett Till”, sparked outrage from the Till family and prompted Sony Music executives to pull the track.
