Anyone who follows Mariah Carey knows she’s had an airtight relationship with her lambs (her dedicated fans) since the beginning of her career. But last night, Carey teamed up with Jimmy Fallon to give a few fans the surprise of their lives.

Fallon invited several groups of them to his studio to hear Carey’s new single, “The Art of Letting Go.” Little did they know, the vocal titan would emerge from the next room singing the ballad!

Their reactions are simply priceless. With tears welling up in their eyes, and looks of disbelief, these lucky, very lucky, fans will never forget this moment.

Check out the video above.
