Concert goers surely had no idea what was in store when 19-year-old Monique Burrell was pulled from the crowd during Jay Z's recent Chicago Magna Carta Holy Grail show and the cool thing about Monique is that she's joined Jay Z onstage once before too.

After being selected from the audience at random, Monique Burrell, who goes by the rap alias MoBoTheGreat, took an audience of thousands by surprise for the second time. MoBo first rapped for Jay at the tender age of 16 during his Blueprint 3 tour. The Chicago native held up a sign this time around that read: "I was 16 when I rapped on stage with you for BP3. I'm 19 and READY"

And ready she was. Her natural stage presence during her impromptu rap set impressed Jay so much, he requested her contact information be collected by head of security, this according to TMZ.
