Jay-Z is furious that Rihanna is getting close to her ex-boyfriend Chris Brown and has warned her that it will not end well.

The ‘Rude Boy’ star has collaborated on two tracks with the her ex-lover amid rumours that they are also secretly hooking up.

As a close friend and mentor to the young singer Jay-Z helped her through the days after Rihanna suffered the horrific attack by then boyfriend Chris Brown in 2009.

At the time Jay-Z was disgusted by the ‘Champion’ star’s actions and has been “dead” to the ’99 Problems’ star ever since.

A source told Radar Online: “Chris is absolutely dead to Jay, he wants nothing to do with him ever. Now that Rihanna is hooking up with Chris and recording songs with him, Jay is deeply disappointed in her actions.”

“He can't fathom why Rihanna is doing the things she is doing. He understands the need for forgiveness, but he is adamant that Rihanna shouldn't forget what Chris did to her.” They added.

It isn’t just the 24 year-old that Jay is said to be concerned about, he is also worried about what her fans will think.

The source went on: “Jay doesn't understand how a man could ever lay hands on a woman; it just goes against who he is and about. Jay wonders what kind of message this is sending to Rihanna's young female fans.”

He has reportedly told Rihanna to end her relationship with her toxic ex-boyfriend as he fears the singer has not dealt with is violent nature.

An insider said: “Jay has told Rihanna he will never give his blessing for what she is doing with Chris. He has told her, this isn't going to end well, it never does. In Jay's opinion, Chris has rage issues that he doesn't think have been dealt with."

But not even Jay-Z can stop the ‘We Found Love’ singer, who won a Brit Award this week for Best International Female, as she apparently doesn’t care what he thinks.

A close friend revealed: “Rihanna knows how Jay feels about Chris, but she doesn't care, she is going to do what she wants."
