The sweetest girl who anyone can possibly know. A little girl who was a fighter and fought for about 6 years. Beautiful, smart, and Justin Bieber's biggest fan. Avalanna was known by millions and fought long and hard, she is now an angel up in Heaven. Great job Avalanna :)
Mrs.Bieber? Oh that's Avalanna!!
