One man just made Mariah Carey cry!
In this emotional scene from Sunday's Mariah's World, Mariah meets a superfan who tells her how much she means to him and how much of an impact she's had on his life.
"I learned almost English because I repeat your letters," he tells Mariah. "And when I have panic attacks when someone shout at me or something, if I don't hear 'Through the Rain,' I cannot go to sleep because in those ten years, I learned all the words."
He continues, "The only voice I heard every night is you. I don't know if you understand what you mean, what you are from us!"
Then in a sweet moment, he gives Mariah a very heartwarming present.
