Jimmy Fallon really loves him some Mariah. So in honor of her newest single, “The Art of Letting Go,” The Late Night host teamed up with his favorite songstress to give super MiMi fans (a.k.a. “Lambs”) a private listening to the latest track. The only catch, was Mariah was in the studio singing the track live and emerged to greet her biggest fans with all of her fabulousness.

The end result? A whole lot of shocked faces and many, many tears. Check out the cute clip below.
