Lady Gaga and Joseph Gordon-Levitt are steaming things up for a duet of "Baby, It's Cold Outside" during Gaga's Muppet Holiday Spectacular on ABC.

The two will dance and sing to an old-school version of the Christmas tune. This time around, Gaga dresses like an actual human being - in a red gown. Levitt was dapper as usual.

Levitt has been a longtime fan of the Mother Monster. A video of the actor covering "Bad Romance" went viral in 2010.
