Iggy Azalea Makes Billboard History Again (@IGGYAZALEA)

Off the heels of her BET Awards debut, Iggy Azalea has made history once again on the Billboard charts.

According to the Smoking Section, Azalea's collaboration with Ariana Grande, "Problem," has knocked her song "Fancy" out of the top spot. She is the third artist to replace her hit with another hit.

Mariah Carey was the first artist to do so with "One Sweet Day" featuring Boyz II Men and "Fantasy" in 1995. Outkast was next with "Hey Ya" and "The Way You Move" in 2003-04.

Her singles have held down the Billboard charts for five weeks, with "Problem" selling close to 2 million downloads, and "Fancy" with Charli XCX 2.3 million downloads.
