It's been one year since Mrs Bieber, Avalanna Routh has left us. Pop singer Justin Bieber remembered her and paid his tribute to the girl who stole his heart and then died on September 26, 2012 of brain cancer. Baby Routh was an avid fan of Justin Bieber and the singer even did a small ceremony to officially announce her Mrs Bieber.

"Will never forget my girl. RIP Avalanna #mrsbieber," tweeted Justin Bieber.

The singer first came to know about Avalanna's tragic story in February 2012 that she was fighting with a particularly difficult form of brain cancer called ATRT (atypical teratoid rhabdoid tumor). The adorable Avalanna was expected to die anytime from this disease so Justin wanted to make her as happy as he could.

The teenager with a big heart was so touched by the story that he arranged to Avalanna and her family to fly to him in New York so he could "marry" the dying girl. In an adorable ceremony, which was captured on video, the two Justin called Avalanna his "angel." All the Bieber fans call Avalanna Routh as "Mrs Bieber" now in the memory of the little girl.

However the "angel" left for the heavenly abode exactly a year back and left fans and Justin Bieber in shock.

"Our darling Avalanna went to Heaven this morning. Oh Avalanna, the brightest star - you took our hearts with you, our greatest Love," Justin wrote on Twitter then and even on Wednesday he remember the girl on the same date she left.

"One of her greatest adventures was meeting Justin Bieber. In typical Avalanna fashion, she was completely unfazed by Justin's fame. She fell in love with a cute boy who was mesmerized by our girl because she radiated life, love, laughter and so much mischief. She was the light of our lives and still shines so bright," wrote Avalanna's mother in a blog post in Huffington Post on Wednesday.

May her beautiful soul rest in peace. RIP Avalanna.
