The co-owner of the Golden State Warriors has revealed that he stopped sitting next to Rihanna during game one of the NBA Finals because the popstar's cheering was annoying him.

Joe Lacob invited the Barbadian singer to sit next to him courtside at the Oracle Arena, but switched seats midway through the game as the 27-year-old shouted her support for Cleveland Cavaliers forward LeBron James.

When asked about his seat switch, Lacob told reporters: "She bought seats, paid a lot of money for them and she can root for whoever she wants, right? But I thought I would be a nice guy and took my two kids, who go to a lot of games and booted them down to the end of the court and moved her next to me.

"I said hey sit next to the owner, it is a nice thing to do. I thought I was being friendly. She was rooting for LeBron the whole game so finally I was getting irritated and I said hey I'm the owner of the Warriors. She didn't care, she just kept going.

"So finally I said that's it and I moved a couple seats down. Everyone has it that I moved my fiancee next to her because she got upset that I was sitting next to Rihanna, which is not true."

Despite Rihanna's support, James's Cavaliers lost the game 108-100 in overtime.
