Fan Fare

Britney Spears celebrates threesomes in new single

Mommy, what’s a threesome? 

If Britney Spears still has any ‘tween fans left, their parents are about to face yet another uncomfortable question pertaining to the pop idol.

The former Disney Channel starlet has just released a new single, “3,” which may be more appropriate for the Playboy Mansion than the Mouse House.

“Three is a charm, Two is not the same, I don’t see the harm, So are you game?” she playfully asks at one point. You can listen to the song here.

The slick ditty should get the kids out on the dance floors, but there’s even something in there for old folkies, since Spears tosses in a head-scratching reference to “Peter, Paul and Mary.” The song was produced and co-written by Swedish hitmaker Max Martin (“… Baby One More Time”), so it’s possible the 27-year-old singer might consider them three random names.

Equally unwittingly, she now follows in the footsteps of Jane’s Addiction frontman Perry Farrell, whose ménage à trois with his girlfriend and a teenage heiress inspired the alternative rock band’s 1990 song “Three Days.”

“3″ comes from “Britney Spears: The Singles Collection,” which comes out on Nov. 24, almost five years after her last hits package. (She released just two albums in the interim.)
