Does Nicki have a problem with Iggy?

Watch out, Nicki Minaj! There's another big bootied rapping babe in town: Iggy Azalea! So, is Nicki jealous that Iggy's "Fancy" has become such a huge hit? "I'm not a hater," Nicki says. "If Iggy's song is charting well, then congratulations." But the veteran "Starships" singer wants respect in return, saying, "I want female rappers to understand that I've kicked in a lot of doors for them and would appreciate if they would acknowledge that."
