Carrie Underwood's Grammy Awards dress kept her covered up from the front, but showed off some sexy skin in the back as she stepped out this afternoon in LA.

Carrie, who is nominated this evening for Best Solo Country Vocal Performance for "Mama's Song," was without husband Mike Fisher for the arrivals. During the show, Carrie will be taking the stage for a duet with Tony Bennet, who is making headlines for his performance at Saturday's somber Clive Davis party. We'll see if he speaks about Whitney Houston again when he and Carrie sing together. For now, weigh in on all the Grammys red-carpet fashion and beauty with Fab and Bella's polls!
