AceShowbiz - Drake has received an official warning from National Basketball Association (NBA) officials over his heckling of players. The Canadian rapper, 31, is an avid Toronto Raptors fan and has been a prominent courtside supporter during their heated NBA playoff series against LeBron James' Cleveland Cavaliers.

In the first match between the teams at Toronto's Air Canada Centre on Wednesday, May 1 he heckled Cavaliers player Kendrick Perkins, who later accused him of "talking s**t." According to USA Today, NBA spokesman Tim Frank said his bosses had issued a warning to the "Hotline Bling" musician, who acts as a Raptors ambassador, as he had fallen foul of measures aimed at cracking down on fan abuse at games.

Perkins told ESPN what Drake had said to him, revealing, "Drake butted in, talking s**t to me. He said something slick, so I said something back: 'Sit your a** down and watch the game.' "

Bruce Arthur, a journalist at the Toronto Star newspaper wrote that the exchange between Drake and the basketball star was even more heated, stating Drake called Perkins a "f***ing p***y' and that Cavaliers security personnel had spoken to his minders.

The hip-hop star later joked about their altercation on Instagram, writing "I just said I liked the hem on his capris [his team tracksuit trousers]."

Toronto lost the game in overtime, having led through the entirety of regular play. They are now 2-0 down in the series after losing again on Thursday, May 03, and need to win four of their remaining five games against the Cavaliers.
