Kanye West crossed the line dissing Beyonce: Jay Z

Rapper Jay Z said he has a problem with Kanye West because he spoke out of line about his wife Beyonce when he went on a huge rant about the pair at his gig at The Forum in California last November.
The pair have feuded ever since West stormed the stage at the 2009 MTV Video Music Awards while Taylor Swift was collecting her award to say he felt Beyonce deserved to win.
However, things got even more heated in November when West went on a long rant, in which he accused Beyonce of only turning up the VMAs because she was to win Video of the Year, reported Digital Spy.

Addressing their spat, Jay Z said, "You got hurt, because this guy was talking about you on a stage. But what really hurt me, you can't bring my kid or my wife into it... We've gotten past bigger issues, but you brought my family into it, now it's a problem with me."
Jay Z, who has three-month-old twins Rumi and Sir Carter and five-year-old daughter Blue Ivy with Beyonce, said he and his rival have had fall outs in the past, but none this big.
"You know it's a problem because me and him would have talked about it, resolved our issues.

"And he knows he crossed the line. He knows. And I know he knows. Cause we've never let this much space go between one of our disagreements and we've had many. That's part of who we are.
