Spears, 33, and Azalea, 24, debuted the song earlier this month. At the time, the rapper admitted that she was having trouble believing that she had the opportunity to work with the pop star.

"To be honest im just over here acting like a total fan girl for britneys vocals on this song," she wrote. "cant. stop. listening. so classically britney."
