He is also being accused of destroying work he did with this other A+ list singer

Apparently this former A+ list rapper turned A- list rapper with a grudge against everyone and everything except a designer and ice cream, is not happy with terms of his loan/buyout.

He basically delayed the record of this A+ list singer by almost a year because he refused to give up the work they had done together.

He is also being accused of destroying work he did with this other A+ list singer who is married to the guy who runs his life.

Kanye West
Delayed: Rihanna
Destroyed work: Beyoncé (Jay Z)
