Rapper Shawn “Jay-Z” Carter is currently sitting on a $150 million Live Nation deal, and he’s newly-wedded to superstar Beyonce - but a former heavyweight champion got news for Hov: the honeymoon is over.

According to Allhiphop.com, former boxer Mitchell Rose has plans to sue the rapper for $88 million for, basically, stealing his style. “He took the style and the delivery,” Rose told AHH. “…All I want is justice. Jay-Z knows what I am talking about.”

Rose, a 39-year-old Brooklyn native, went on to say that he slipped Jay his demo at a William Joppy and Felix Trinidad fight. He later said he heard his style smeared all over Jay’s songs, a whisper sound that Rose claims is his.

“I had previously trained some of my artists to use that style, but it quickly became obsolete after Jay-Z got a hold of it,” Rose says. “He [Jay-Z] used the whispering to enhance his music and financially benefit from it. Jay-Z disregarded the fact that it was my demo where he got the style from as he went on to use it for his own personal gains, which is wrong.”
