Justin Bieber made a cancer-stricken girl`s dream come true

The `Baby` singer surprised six-year-old Avalanna Routh - who has battled deadly brain cancer since she was a baby - by flying her and her family from Boston to New York to meet him after reading her request on Facebook.

The pair then spent the afternoon playing board games, eating cupcakes, and signing autographs for each other before deciding they would get `married`.

When asked how long she had loved Justin, Avalanna - who has undergone chemotherapy and radiation treatments - said: "Seven years. No - 80 years."

Justin - who is dating Selena Gomez - later wrote on his twitter page: "That was one of the best things i have ever done. she was AWESOME! Feeling really inspired now! (sic)"

He then added: "#MrsBieber really inspired me."

Avalanna`s mother Aileen said the meeting had been a dream come true fro her daughter.

She said: "It was wonderful, just another fun moment."

Speaking of Avalanna`s cancer, Aileen added: "She`s beaten all the odds. It`s a very aggressive, rare disease, and she`s been in treatment for five and a half years."
