Britney Spears debut her new single "3" today. I love it already. It's stomping clubby number, backed with synthetic horns and the rest of it. It reminds me of "Brave New Girl" from the, In the Zone, album. "3" is the first (and possible only) single to be released from Spears' forthcoming Singles Collection, out November 24. And yes she's talking about threesomes.
