Rapper Iggy Azalea has scored a fourth week at the top of the U.S. pop charts with her summer hit Fancy.

The Australian also extends her one-two punch atop the Billboard Hot 100 because Ariana Grande's hit Problem, on which she features, stays put at two as well for a fourth week.

Only the Beatles held the countdown's top two spots with their first U.S. releases in the same week back in 1964. Iggy has another eight weeks to go to match their record.

Canadian four-piece Magic! rockets into the new top five at three with their hit Rude, while John Legend's ballad All of Me drops a spot to four and Jason Derulo's Wiggle holds at five.
