Haley Reinhart and Casey Abrams of 'American Idol' Record a Christmas Duet!

Halloween is only just over, but the stores are already putting out their Christmas decorations. Not only that, but singers are starting to put out their holiday hits as well, with Justin Bieber releasing a couple of tracks and Zooey Deschanel's new She & Him Christmas album hitting shelves.

Not to be outdone, a couple of "American Idol" finalists have teamed up to release their own holiday track... and no, it's not Scotty McCreery and Lauren Alaina (though I'm sure that duet is coming up soon). No, it's jazz enthusiasts and rumored lovebirds Casey Abrams and Haley Reinhart!

The two were eliminated from "Idol" before the big finale (Abrams was eliminated twice, since the judges used a save on him), but still made it far in the competition and were much-loved by the fans. With their jazzy styles and warm yet raspy tones, it seems only fitting that they would pick up a Christmas classic.

The duo chose "Baby It's Cold Outside," a favorite that shows up time and time again in pop culture... Zooey Deschanel sang it with Will Ferrel in "Elf," and Darren Criss crooned with Chris Colfer on "Glee" last year.

You can hear a 90-second preview of the song (enough for the first verse or so) over at Entertainment Weekly.
