Jay-Z: 'Brown is a walking dead man'

Jay-Z has issued a warning to Chris Brown amid allegations that he assaulted girlfriend Rihanna.

The rapper called Brown a "walking dead man" after learning that the 'Umbrella' singer had suffered "horrific" injuries in an alleged altercation earlier this week.

"Chris is a walking dead man. He messed with the wrong crew," he told Us Weekly.

Meanwhile, Kanye West has admitted that he was "devastated" by the news.

"It’s so devastating, that should never happen. I feel like [Rihanna's] my baby sis and I would do anything and everything to help her in any situation," he told KIIS-FM.

Brown has been charged with one count of making felony criminal threats. He was freed on $50,000 bail and will appear in court on March 5.
