Rihanna and Chris Brown: Jay -Z Threatens To End Chris's Career If He Hurts Rihanna 'Emotionally or Physically'

Jay-z threatens Chris Brown after his show at the Barclay Center. The Rapper reportedly invited Rihanna and Chris Brown back stage once the show was over and exchanged some words with Chris Brown.  According to Bossip.com, a source said "He invited them as a couple to his concert in New York and backstage and he called Chris to one side and told him if he hurts Rihanna, whether emotionally or physically, it's over for him."

Recently, friends are worried that the newly single Brown will soon make an appearance with Rihanna and go public with their relationship. Sources told Life & Style, "Rihanna and Chris just have that young, crazy, toxic love." They added, "They never really grew up."

Chris is still on probation for giving Rihanna a black eye, split lip, and a head contusion in 2009.  Rihanna's friends believe the bad boy is not a changed man, "Chris is the same guy he was when the attack happened. He's volatile. It's scary. This time she knows exactly who he is, and she's walking right back into it," a source told Life & Style.

Before officially breaking off his relationship with Karraueche Tran, Brown talked about his love for two unidentified women and asked if it were possible in a video confessional. Friends of Rihanna fear that she will go down the same road if the two make it official.  However, Jay-z seems to stand by her decision telling her, "if Chris is truly making her happy then go for it," one source said.

Hopefully, Chris doesn't mess up this time around. He just won the public's heart. Don't know if they'll be to accepting a second time around.
