This one is almost too easy! In the Amazon Kindle Fire HDX 2013 commercial, a little girl is ensconced in her Kindle and what she sees comes to life in a Christmas card -- namely singer Kelly Clarkson, who sings her new Christmas hit, with a swipe of scarlet lipstick on her pout. The singer is totally in the Christmas spirit as she sings. So what's the song?

The song that Clarkson is singing is the catchy, upbeat and uptempo 'Underneath the Tree' from her first holiday set, 'Wrapped in Red,' which was released earlier this fall. It's this season's 'All I Want for Christmas Is You.'

Kindles are likely on the holiday wish lists of lots of book and music fans, and Clarkson's song rings in the holiday spirit in a super festive way. Plus, any time we get to see her on the small screen --and in this case, a really small screen -- is fine by us.
