Jay-Z threatens to "finish" Chris Brown if he hurts Rihanna again

Jay-Z has issued Chris Brown with a stern warning that if he ever hurts Rihanna again, he will "finish" him.

 It's been revealed that the Roc Nation boss gave the 23-year-old a harsh dressing down backstage when he attended one of his Barclays Centre concert nights with Rihanna. "Jay-Z told Rihanna that if Chris is truly making her happy then to go for it," a source told The Sun newspaper.

 "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," the sources added. 

 It's been rumoured that Rihanna and Chris - who ditched his model girlfriend Karrueche Tran earlier in the year - plan to make their relationship public knowledge in the next month. "He'll ensure it will result in the end of his career," the source added.
