Kanye West and Jay-Z are reportedly preparing for a heated court battle against each other. According to an insider, the "Famous" hitmaker is planning to sue the "Empire State of Mind" rapper over a money dispute.

A source tells Life & Style, "Kanye believes he's owed by Tidal and he will fight for it. There's no salvaging the friendship, so Kanye's go ing full force. He could reveal secrets about JAY-Z that may not be pretty."

The source reveals that Jay-Z could do the same. "Jay would rather settle this man-to-man, but it's gone beyond that now. This is war."

While he's upset about his deal with Tidal, Kanye's resentment stems from JAY-Z and Beyonce's decision to skip his 2014 wedding to Kim. "Kanye thought his children would grow up with Jay's kids [Blue, 5, and 2-month-old twins Sir and Rumi]," the source continues, "[When he realized that would never happen] Kanye was really hurt. He feels Jay used him for his music."

According to the source, Kanye has shown that he's willing to sue for money he believes he's entitled to. "This isn't some little dispute, not in Kanye's eyes," explains the source, "Kanye feels deeply betrayed by JAY-Z. This will get settled in the courtroom."
