American Idol's Haley Reinhart & Casey Abrams to release Christmas duet!

American Idol Season 10 finalists Haley Reinhart and Casey Abrams will be releasing a holiday duet this Christmas season. The two will sing a jazzed up "Baby, It's Cold Outside."

The song will be available on November 21st, and the pair have also recently shot a music video for the new song!

Again I say, November 21st will definitely be a big day in the music world. Not only will this new duet be released, but so will Haley and Casey's fellow Idol pal James Durbin's debut album Memories Of A Beautful Disaster, as well as Daughtry's new album Break The Spell and Big Time Rush's new album Elevate.
