Pop superstar Britney Spears' demo of Pitbull's "Hey Ma" reportedly leaked online on Dec. 21. Bachata king Romeo Santos is also featured on the track.

"Hey Ma" was the lead single on this year's "The Fate of the Furious" soundtrack. Pitbull let it be known that Spears and Santos were originally featured on the track, but that the "Furious" team opted to replace them with former Fifth Harmony singer Camila Cabello and reggaeton superstar J Balvin. The Spanish version of "Hey Ma" with the revised trio peaked at No. 5 on Billboard's Hot Latin Songs chart.

Those wondering how Spears and Santos sounded on "Hey Ma" apparently have to wait no longer as the original demo with both acts appears to have surfaced online. The tropical beats are similar with Pitbull introducing Romeo and "Britney, b*tch!" Santos singing in English is still as sultry as when he does in Spanish. Spears keeps things flirty and fun on her guest verses. "If you touch me right then I might stay the night," she sings. "Ma" should have been serviced to multiple markets with Britney and Romeo on one version and Camila and Balvin on another.

In other Spears news, she is wrapping up her four-year residency at Planet Hollywood on New Year's Eve with the final Piece of Me show. Britney will also perform as part of Dick Clark's New Year's Rockin' Eve with Ryan Seacrest on ABC.
