Britney Spears is making the most of her sex symbol status, again. This morning (Sept. 29), the one-time Disney Channel child star whose personal life has at times eclipsed her musical output, premiered "3," a new single about the pleasures of polyamory, on New York radio station Z-100. The song goes to radio everywhere today and is part of "Britney Sears The Singles Collection," a hits compilation due Nov. 24 on Jive.

Produced by Swedish hitmaker Max Martin (Katy Perry, Kelly Clarkson), "3" finds Spears singing about the racy subject of a ménage a trios with her signature coy delivery. "Three is a charm, two is not the same," Spears coos seductively on the verse. "I don't see the harm, so are you game?"

"Britney Spears The Singles Collection" marks 10 years since Spears released her breakthrough debut album, "...Baby One More Time," which spent 103 weeks on the Billboard 200 chart and has sold 10,554,000 copies, according to Nielsen SoundScan. Two versions of "The Singles Collection" will be released: a standard one featuring 17 of Spears' biggest hits along with "3," and an "ultimate fan box set" with all 29 of her singles, a DVD of her music videos, and a booklet featuring classic images.

Spears wrapped the second North American leg of her "Circus" tour on Sept. 27 in Las Vegas.
