When it comes to fans, 18-year-old singing sensation Justin Bieber has more than his fair share.
But when the teen heartthrob stopped by "Access Hollywood Live" this week, he mentioned one particular fan who made an impression on him -- a young girl with brain cancer who calls herself "Mrs. Bieber."
"Basically, she think I'm her husband, and she thinks we're going to get married and live happily ever after," Bieber said.
He told "Access Hollywood" that his fan even staged an entire wedding with a cut-out version of him as the "groom."
