Jimmy Fallon is always up to something, this time round he has recruited singing sensation Mariah Carey to join in his latest antics.
Fallon invited a group of Mariah’s super fans, affectionately known as ‘Lambs’, to exclusively hear her new song, but of course that wasn’t all.
Mariah made a surprise entrance into the area where the fans were seated half way through the track.
The reactions, well they’re just priceless.
