Kendrick Perkins and rapper Drake had to be separated after a courtside confrontation in Toronto - twice.
Drake is a regular fixture at Raptors games and often inserts himself into proceedings by converting with players and referees.
Perkins clearly didn't appreciate something that was said and had to be pushed away by teammate JR Smith at halftime of Cleveland's 113-112 win. Jose Calderon, of all people, was on hand to stand in front of Drake.
The jawing resumed after the game. Toronto Star sports columnist Bruce Arthur heard Drake call Perkins a "f***ing p****" and described the rapper as "mad".
