Written and produced by the Invisible Men (Iggy Azalea, Rita Ora, Jessie J), the song first surfaced from a leak on Friday in advance of a unique premiere by Spears.

The singer officially debuted the track over the weekend in a promotion involving Uber. Fans in Los Angeles were able to request a "Bee" branded Uber SUV and preview the song as many times as they wanted before their ride ended, making the singer the first artist to use Uber to release a single.

Last week, Spears injured an ankle in a fall during a performance of her Las Vegas residency show, "Britney: Piece of Me." The singer was forced to postpone her May 1 and 2 concerts under doctor's orders to allow time for the injury to heal.
