Some people question Justin Bieber's authenticity and his love and dedication to his fans. Well his relationship with 6-year-old Avalanna Routh, who called herself "Mrs. Bieber," proves how much love he truly has. Justin, along with his family, crew, and all of his fans, have very sad hearts today. The adorable Avalanna passed away this morning from a rare form of brain cancer.

Avalanna's dreams came on Valentine's Day of this year. Justin Bieber got word of her disease and her love for him and flew her out to spend a day with him in New York. And it wasn't just a hello-goodbye type thing, they spent the whole day together. They played board games, ate cookies, goofed off, and just had a blast.

That wasn't the end, though. The two developed a strong bond and friendship, with Beiber shedding light on the rare disease that in the end took this precious girl's life. The two were on Good Morning America this past summer, and she hung out with him backstage at his sold out show at the Apollo. That night he even brought her on stage and sang his hit "One Less Lonely Girl" to her.

Whether you are a Belieber or not, just watching this video you see how much this girl means to him. In the video below, he talks about her and his love for her. He gets teary when he says "Avalanna means the world to me. She has a condition where she probably won't make much longer. It hurts sometimes to think that I might not be able to see her again."

In 2006 Avalanna was diagnosed with AT/RT, which is one of the rarest forms of brain cancer. AT/RT is most commonly diagnosed as brain cancer, but can be found elsewhere in the nervous system, such as the spinal cord. Unfortunately, there is no cure for AT/RT.

Justin has taken to his Twitter this afternoon to express his grief.


Here is a video all about Avalanna and Justin, and just how special this little girl was. She touched many hearts. We send our condolences and prayers to the Routh family, along to Justin and his entire crew.
