All the single ladies, all the single ladies. For this year's Grammys, it's all about the single ladies - and the married one, too.
Beyonce, whose "Single Ladies (Put a Ring on It)' is up for song of the year, leads all artists at Sunday night's ceremony with 10 nominations. Taylor Swift, whose multiplatinum "Fearless' was the top-selling album of 2009, is up next with eight nominations. Other top nominees include Lady Gaga, with five nods, and Colbie Caillat with four. It's the first time female artists have been the top two Grammy nominees since 1999, when Lauryn Hill, Sheryl Crow and Shania Twain led the night.
