Holy Maury, Mother of God! One Selena Gomez fan got the surprise of a lifetime on the daytime TV staple -- and no, it wasn't a paternity or polygraph result (those are reserved for her ex, Justin Bieber). It was a message from the singer herself!

Gomez delivered a moving message and special surprise to a young lady named Hannah, who suffers from primordial dwarfism, for the teen's 18th birthday and to celebrate the 2,500th episode of 'Maury.' It was Hannah's seventh appearance on the show -- and we're willing to bet her favorite one, too.
