If you were able to look back through your history, there's a chance you had a brush with someone famous, only it happened before they were famous. Rosie O'Donnell encountered a beautiful little girl named Mariah years ago, as she explained on 'The Rosie Show' (Weeknights, 7PM ET on OWN). Even after Mariah Carey blew up on the music scene, O'Donnell didn't make the connection.

It wasn't until someone pointed out that Carey had grown up on a certain street that O'Donnell realized it was the same little girl she used to sing to at the bus stop. It's just kind of crazy to imagine what some of the people you've encountered along the way may have gone on and done with their lives -- and you don't even know you knew them way back when.
