With their saxy new single "Problem," Ariana Grande and Iggy Azalea just made history by notching the highest debut ever between female soloists. Coming in at No. 3 on the Hot 100, the collaboration also scored the eighth-largest debut for downloads, selling 438,000 digital copies last week. 

And just a chart position lower than "Problem" is "Fancy," Iggy's collabo with fellow female badass Charli XCX. You go, girls.
