I think Nicki will get one eventually. All it'll take is for her to get on a pop girl collab for a lead single (or get a pop girl on her lead/second). Bound to happen
Yes cause there is no other female rapper with her talent. I think it's possible Nicki could try with a feature. She came close with The Hills and Bang Bang but didn't quite make it. But as lead artist 100% nobody will beat Iggy.
