I don't know if it's for her, but the all black made me think of Adele.
I wouldn't be surprised if she covered it again. Her US version was the second biggest selling issue of the year in 2012 (after the Sept. issue) and Anna loves her. Plus they love to have people cover it when they make their returns. Gaga covered it before BTW came out and Bey covered it last year originally for her album (though it got pushed back).
