Iggy Azalea has scored another chart record in the U.S. by becoming the first female rapper to land six weeks at number one with the same tune.

The Fancy hitmaker became the first act to score a one-two punch at the top of the countdown with her chart debuts, and now she's the Billboard Hot 100's queen of rap.

She passes Lil' Kim, who spent five weeks at number one with the all-star collaboration Lady Marmalade in 2001.

Meanwhile, Magic!'s Rude rises a spot to two on the new chart, swapping places with Ariana Grande's Problem, which features Azalea, and pop duo Nico & Vinz's Am I Wrong stays put at four.

Sam Smith rounds out the new top five with Stay With Me.
