Jay Z -- Latest Concert Find Could Land Record Deal

The fan who was pulled onstage Thursday and rapped at Jay Z's concert says something happened afterward that could land her a recording deal with Hova himself.

Monique Burrell (rap name is MoBoTheGreat) tells TMZ after her impromptu performance -- which brought the house down -- the head of Jay's security team approached her and asked for her digits. The guy told her Jay personally wanted him to get her number so he could follow up later.

So far ... no call. But it IS unusual for the rap mogul to ask for the phone number of the people he pulls up on stage.

You may recall ... last week Jay pulled a 12-year-old boy up on stage who also killed it -- but sadly no numbers were exchanged.

As for MoBo -- cross ya fingers.
