Girl who called self 'Mrs. Bieber' dies of cancer

A 6-year-old Massachusetts girl whose love for Justin Bieber encouraged physicians and nurses at a Boston hospital to organize a pretend wedding to the pop star as she battled a rare brain cancer has died.

The family of Avalanna Routh - who called herself Mrs. Bieber - said on their Twitter account that she died Wednesday morning. "Oh Avalanna, the brightest star - you took our hearts with you, our greatest Love," the family wrote.

During the pretend wedding, Avalanna held a yellow, green and purple bouquet of flowers, wore a T-shirt that said "Future Mrs. Bieber" and stood next to his portrait under a banner that declared them "Just Married." That sparked a social media campaign to help her meet the singer.

Bieber later arranged for the girl to meet him in New York, where they spent a couple of hours together before he tweeted that the experience was inspiring and the best thing he's ever done.

"... she was AWESOME! Feeling really inspired now! (hash)MrsBieber," he tweeted.

Bieber took to Twitter to mourn the death of Avalanna.
