We all know that Rihanna and Chris Brown have been hanging out again and that the young couple will most likely re-kindle their romance, but not everyone is happy about the two young superstars being around each other as of late. The one person not too happy about the situation---Jay-Z.

According to The Sun, Jay-Z has taken on the big brother role now that his protégé has made the questionable decision to reunite with Brown. If you recall, Brown left Rihanna bruised and battered after an altercation while they were dating.

As we previously reported, Brown and RiRi recently attended a Jay-Z concert, and it was then that Jay-Z issued a stern warning to Chris Brown. Sources say Jay-Z took the opportunity to address the young duo and warned Brown that "he would finish" him, Brown, if Brown ever hurt Rihanna again. Jay-Z promised to end Brown's career if he hurt Rihanna.

Jay-Z told Rihanna that if Chris is truly making her happy then to go for it," a source told the paper. "He invited them as a couple to his concert in New York and backstage he called Chris to one side and told him if he hurts Rihanna, whether emotionally or physically, it’s over for him. He’ll ensure it will result in the end of his career."

Its no secret that Jay-Z was NOT happy with Brown after he beat Rihanna, but what has made him change his mind about the young superstar---maybe time truly does heal all ill feelings. In any case, it will be interesting at all levels to see how all of this eventually plays out. We certainly hope that we do not see a repeat of their abusive relationship.
