Carey later treated the devotees to a private concert to thank them for their continued support.

Carey credited Fallon for successfully pulling off the stunt, confessing she "was not feeling up to it", but admitted she had a great time interacting with her biggest supporters.

I don't even get to do that in front of my friends... Thank you for letting me do that because I didn't know what it was going to be (like)."
