What is likely to be one of this year's Songs of Summer, Iggy Azalea's "Fancy," has reached No. 1 on the American charts.

While Billboard has yet to make it official as of this writing, the rapper revealed on Twitter that her Charli XCX-featuring single has topped the Hot 100 after peaking at No. 2 last week behind John Legend's "All of Me."

Def Jam also confirmed the news Wednesday morning.
