Jay Z is making more dreams come true. After inviting 12-year-old Justin to rap for him on stage in Greensboro, the Roc Nation mogul gave another fan a second shot at impressing him. TMZ caught the performance during his “Magna Carter World Tour” at Chicago’s United Center last Thursday night (1/9). The fan was 19-year-old female MC Monique, who previously rapped for him at the “Blueprint 3″ tour when she was 16. After expressing the hell she went through to get to the concert, the confident teen grabbed the mic and gave it her all. While Jay didn’t offer her a record deal, he did respond with some encouraging words. “You just told your whole entire life story, huh?” he said. “I would’ve done the same shit. F**k that. It might not happen again.” He gave her a big hug and said, “I love you,” before she made her way off stage.
