But the best part about the song is its adorable music video. The clip stars two kids dressed up as adults lip syncing Idina and Michael's powerhouse vocals.
"Baby, It's Cold Outside" is the only duet on Idina's album, which arrived last month. It also features Idina's versions of holiday standards like "Have Yourself A Merry Little Christmas," "Silent Night" and "White Christmas."
