Casey Abrams, Haley Reinhart have fun behind the scenes of duet

They’re back!

If you loved watching season 10 of “American Idol,” it’s pretty likely that you enjoyed at least one song by either Casey Abrams or Haley Reinhart — then again, it’s also pretty likely that you thought their duet of “Moanin'” was one of the best things to grace the show over the course of the entire season.

With this in mind, the two are re-teaming for a new duet of “Baby, It’s Cold Outside” — and we have a new behind-the-scenes video that proves that the two parties are having more than a little bit of a good time together. You can check it out below, and just the introduction (which features a fake phone conversation between the two) is worth watching just for the laughs alone.

This duet is going to be made available on iTunes on November 21 — so be sure to remember it in the midst of every other music release that is coming out that day (and there are plenty).
