Brit-news!BRITNEY SPEARS HAS CONFIRMED via her Twitter account that her new single, “Hold It Against Me,” will be released next Tuesday, January 11! The 29-year-old pop princess tweeted, “Heard an early demo of my new single leaked. If u think that’s good, wait til you hear the real one Tuesday.” Although an early demo of the track, produced by her longtime producers Max Martin and Dr. Luke, did leak today, the vocals clearly do not belong to Britney. The single’s release will finally put an end to over a year without a new Britney tune (how have we survived?!). Her last official album, her second greatest hits anthology The Singles Collection, came out in November 2009. That included the track “3,” which was her last #1 hit.
