Britney Spears seems to have decided once and for all to step out of any sort of promotion for her new record. Originally, Britney had plans for a hosting gig on Saturday Night Live in December, according to Us Weekly, as well as a surprise appearance at the American Music Awards. But all of those plans have been cancelled according to a rep close to Spears. Britney also had tentative plans to go to the UK sometime in December to promote, ‘Greatest Hits: My Prerogative,’ as well as her smash hit perfume, ‘Curious.’ Those plans have also been cancelled for now. Not only that, but Britney has cancelled a new single. The brand new track on her hits album, ‘Do Somethin,’ was scheduled for radio release in December along with a video in January. But Brit cancelled the release so she could focus on family life. For now, a promo video of a brand new, ‘Megamix,’ has been sent out.
