Girl who called self 'Mrs. Bieber' dies of cancer
The family of Avalanna Routh -- who called herself Mrs. Bieber -- said on their Twitter account that she died Wednesday.
Her pretend wedding to Bieber led to a social media campaign to help her meet the singer.
Bieber later arranged for the girl to meet him in New York, before he tweeted that the experience was inspiring and the best thing he's done.
Avalanna suffered from an atypical teratoid rhabdoid tumor. Only 30 new cases are diagnosed in the U.S. each year.
Bieber mourned the death of "one of the greatest spirits I have ever known," saying in a tweet: "RIP Avalanna. I love you."
