The Womanizer singer, who is known for wearing revealing, skin-flashing outfits on stage - has penned a track called “3” which suggests she likes being intimate with two lovers at the same time.
On the track, Britney sings: “Three is a charm / Two is not the same / I don’t see the harm / So are you game?”
The chorus continues: “One, two, three / Not only you and me / Got one eighty degrees / And I’m caught in between.”
“Countin one, two, three / Peter, Paul and Mary / Getting down with 3P / Everybody loves ***.”
The racy song is due to appear on Britney’s upcoming LP “The Singles Collection”.
This is not the first time Britney’s career has taken a provocative twist.
The 27-year-old star, who as a teenager said she wouldn’t have sex before marriage - is currently on the road with her steamiest world tour to date.
'The Circus Starring Britney Spears' - which received rave reviews - features skimpy costumes, seductive dance moves, whips, latex and blindfolds.
