We hope you're sitting down for this, readers: the new smash hit from Fergie is NOT about a bridge in London; nor does it refer to a nursery rhyme.
Evidently, "London Bridge" refers to a sexual act of some sort. Yes, Jack Nicholson would be proud of the member of The Black Eyed Peas.
The song, which is included on her debut solo album "The Dutchess," refers to when two women and two men have sex and form a position to make a "bridge." We're having trouble picturing that, too, don't worry.
Despite writing about the racy subject, Fergie insists she has never participated in the act.
"Have I ever been involved in one? No I don't think I ever have actually. No, no I haven't," the singer said. "But I'm definitely touching on issues that aren't childlike!"
Gosh, we hope Sutton Pierce Federline isn't listening in that case.
In the chorus of the song, Fergie sings, "How come every time you come around, my London Bridge wanna go down?"
The Gossip just figured it was our natural good looks.
