Does Jay-Z have a sister he didn't tell us about in his famous song "Momma Loves Me?"

A woman claiming she's Jigga's sister, recently crashed a news broadcast as the reporter attempted to update viewers on the status of commuter trains following Hurricane Sandy. 

With a somewhat crazed look in her eye, the woman yells:

"Hi, I'm Jay-Z's sister! He was looking for me on the subway!"

The reporter is shocked but tries to keep reporting, which honestly doesn't work out too well for her. 

Could she be a long lost sibling of the rapper? We honestly don't think so... but watch the footage posted above anyway.

There's no way you won't laugh!
