Jay-Z has ended his friendship with basketball star LeBron James after his controversial decision to move from Cleveland Cavaliers to Miami Heat, according to reports.

The hip hop mogul and co-ower of New Jersey Nets used to have a "close" relationship with the NBA star but after his transfer announcement last month, Jigga wants nothing to do with him, according to Media Takeout.

A source said: "Jay-Z was supposed to be able to bring stars to [the New Jersey] Nets - or at least have access to them. [During the time that LeBron was making his decision] he didn't even take [Jay-Z's] calls. It made him look like he couldn't deliver to the Nets management.

"If [Jay-Z] would have landed a star player, he could have been seen as a legitimate asset to the team. Now they see him as just dead weight."

Do you think Jay-Z was wrong for assuming he could persuade James in the first instance?
