A duo we didn't see coming! Last night the powerhouse performed the holiday classic 'Santa Claus is Coming to Town with Michael Buble' and it's pretty beautiful.
The duo were backed by a swinging jazz band and performed the classic as it's original arrangement so everyone could sing-along at home. This may be our new favourite rendition.
Buble headlined the annual NBC special, Christmas In New York, and brought a few very famous friends along to help including Barbra Streisand, Ariana Grande and Miss Piggy.
Ariana also took to the stage alone to perform the Wham! holiday hit 'Last Christmas'.
The pint sized powerhouse released her own film clip for the song 'Santa Tell Me' this week, she sure does love Christmas!
