CeeLo Green and Rod Stewart teamed up to record "Merry Christmas, Baby" for Green's 2012 Christmas album, "CeeLo's Magic Moment," and the two reunited to sing the track as part of the "CeeLo & Friends" holiday special in Las Vegas.
Watch above as the "F--- You" singer takes the stage in red leather pants to introduce Stewart to the Planet Hollywood Resort and Casino audience.
Green's "Magic Moment," which hit shelves at the end of October, has sold 47,000 copies, according to Nielsen SoundScan. In addition to the duet with Stewart, the album features collaborations with Green's "The Voice" co-star Christina Aguilera ("Baby, It's Cold Outside), Disney's Muppets ("All I Need Is Love), and a cappella group Straight No Chaser ("You're a Mean One, Mr. Grinch").
The Muppets also joined CeeLo and a group of contestants from "The Voice" on stage for the Las Vegas event.
"CeeLo's Magic Moment" is a 14-track release with classic holiday songs like "This Christmas," "Silent Night," "All I Want for Christmas" and "Mary, Did You Know?"
