Move over, Mariah Carey. Ariana Grande's coming to town.
We think it's safe to say that we can crown petite songstress Ariana Grande as the new princess of Christmas.
Ariana recently released her super catchy, super cute Christmas themed-single "Santa Tell Me", plus that adorable music video. And now she's going around singing Christmas carols everywhere!
Last night, Ariana was a special guest on "Michael Buble's Christmas in New York". She sang "Santa Claus is Coming to Town" holding hands with the man of the night Michael Buble, and then took the stage by herself to belt out "Last Christmas".
You can watch Ariana sing "Last Christmas" at 9:20, and her duet with Michael at 12:40:
