Britney Spears new song is about having a threesome.
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.
