“Mrs. Bieber” Avalanna Routh Loses Battle with Brain Cancer

Hump Day Wednesday comes with a serious case of “The Sads” for Beliebers: Avalanna Routh — the pint-sized dynamo so enchanted with pop star Justin Bieber that she adopted his sir name as her own — passed away on Wednesday from a rare form of brain cancer.

Her grief-stricken family made the sad announcement on her Twitter account today:

“Our darling Avalanna went to Heaven this morning. Oh Avalanna, the brightest star – you took our hearts with you, our greatest Love;( “

After hearing of her death, Justin tweeted:

“Just got the worst news ever. One of the greatest spirits I have ever known is gone. Please pray for her family and for her. RIP Avalanna. I love you.”

Avalanna, 6, had an aggressive form of brain cancer called atypical teratoid rhabdoid tumor (ATRT). The Merrimac, Massachusetts native was diagnosed with a brain tumor when she was just eight months old.

Routh’s cancer is so rare there are only about 30 new cases diagnosed in the United States each year. Currently, there is no treatment for this type of cancer.

“Mrs. Bieber” met The Biebs after a social media campaign led to a surprise Valentine’s Day date between the pair in New York City last February. In an effort to make Avalanna’s wish come true, her family and friends set up a Facebook page and Twitter account to share her story in the hope of getting Justin’s attention.

And it worked.

Avalanna’s dream became reality when Justin’s manager Scooter Braun got word of the campaign and promised he would make the meeting happen. Scooter flew Avalanna and her family from Boston to New York for a private meeting with Justin just three days later.

In a heart-warming gesture, the Biebs met the little girl and spent two hours playing board games, hanging out, exchanging autographs and eating cupcakes. Avalanna tussled J.B.’s hair, gave him a peck on the cheek and got tossed up in the air.

“That was one of the best things I have ever done. She was AWESOME! Feeling really inspired now!” Justin tweeted after their meeting, posting links to a few pictures from the day.
