Jay has stayed mum on the whole Chris Brown/Rihanna assault case, but sources close to the singer say "He hit the roof" when he first found out about it.
"Chris is a walking dead man. He messed with the wrong crew," the friend added.
Rihanna is Jay-Z's protégé. He found her, took her under his umbrella and made her a star. And thanks to an argument with her boyfriend, she had to spend her weekend in the ER. Let's just say that didn't go over well with the king of hip-hop.
A lot of people are really upset about the whole situation. Note to Jay: we hear he's hiding out in Virginia, just in case that information interests you.
