On Wednesday, Justin Bieber announced the sad news of the death of his biggest fan. 6-year-old Avalanna Routh, better known for the title of “Mrs. Bieber”, has lost the battle with cancer. The “Boyfriend” singer asked his Twitter followers to pray for her and her family.

Grimm day on Wednesday for pop star Justin Bieber. The little girl whom he pretended to marry in a ceremony staged by doctors and nurses at a Boston hospital last year, died of a rare type of cancer.

“Just got the worst news ever. one of the greatest spirits i have ever known is gone.”, he wrote on his twitter page. “Please pray for her family and for her. RIP Avalanna. i love you.” The singer asked for respect of privacy for Avalanna’s family and added: “say a prayer for her and for them. i miss her.”

The 6-year-old “belieber” entered the media spotlight last year when, while admitted to a Boston hospital, she got her greatest wish: a make-believe wedding ceremony starring her and her crush, Justin Bieber.

 

“Mrs. Bieber” dies of cancer at age 6

 

This year, the singer visited “Mrs. Bieber” just one day before Valentine’s Day, in New York. They hung out, played board games and he even let her play with his hair. Bieber says that they were in touch constantly, via FaceTime and iChat.

Avalanna Routh’s doctors at the Dana-Farber Cancer Institute spoke to the Associated Press about the girl’s illness. She had been diagnosed with a rare form of teratoid rhabdoid tumor at the age of 18 months. At first, the cancer treatment was working but in time, her body became less and less responsive.

Avalanna passed away at her home in Merrimac, Massachussets. Her death was sadly announced by her family on Twitter: “Our darling Avalanna went to Heaven this morning. Oh Avalanna, the brightest star — you took our hearts with you, our greatest Love.”

The Dana-Farber Cancer Institute issued a statement as well: “She was a very courageous young person who lived her life with grace and determination”, the statement read. “By generously sharing her story, she raised awareness worldwide about atypical teratoid rhabdoid tumors and articulated the need for greater research of this rare cancer.”
