Who's that woman rapping about her black president, blue Prius, dropping racks at Nordstrom's and is reluctant to use the N-word on Childish Gambino's new mixtape? It's none other than 30 Rock star and Saturday Night Live alum Tina Fey.

Childish Gambino is the stage name used by Community actor Donald Glover for his rapping projects.

Glover has professional ties to Tina Fey, having been a writer for 30 Rock before getting his break on fellow NBC sitcom Community, Gossip Cop reported.

The rapper's new mixtape, Royalty, was released yesterday and features Tina Fey showing off her lyrical talents towards the end of the song Real Estate. The audio of Tina Fey wrapping, which could be heard below, starts at around the 5-minute mark on Real Estate. The full mixtape can be loaded on Glover's website here.

We ballin' so we f----- up the hardwood, homie, Tina Fey raps. This is the life we live, son. My president is black and my Prius is blue, mother-----. Royalty all day. We droppin' racks at Nordstrom's son. That's racks on racks, damnit - you feel me?

Fey then parodies other aspects of hip-hop mixtapes towards the end of Real Estate.

This is the part where most people would say something crazy and drop the N-word after it, she says. Not going to, not gonna do that, I don't feel comfortable. I'm out.

Twitter users were anxious for the release of Royalty and commended Tina Fey for her rapping skills on the Childish Gambino mixtape.
