Avalanna Routh, a six-year-old girl with a rare form of cancer called AT/RT, met her hero Justin Bieber on Feb. 13, making her dreams for Valentine's Day come true.  Bieber flew the little girl to Manhattan for a day of fun (video below).

Her family had launched an online campaign for her to meet Bieber: a Facebook page called 'Get Avalanna to Meet Justin Bieber' was formed, and a Twitter account called TeamAvalanna was created. They caught the eye of a friend of Bieber's manager.

During their Valentine's Day "date," Bieber and the little girl played board games, signed autographs for each other, shared cupcakes and Sour Patch Kids candy. Bieber let Routh play with his signature haircut (picture below).

Later, Routh's nurses at the Jimmy Fund clinic in Boston, Mass., threw her a pretend "wedding" to the singer complete with bridesmaid, a wedding cake, a cardboard cutout of Bieber and a shirt with the words "Future Mrs. Bieber" printed on the front.

Aileen Routh, Avalanna's mother, was overwhelmed by the singer's generosity. She began the Bieber campaign to help distract her daughter from her cancer treatments: "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."

For her part, Avalanna told NBC News: "I got Bieber fever." she told NBC News.

Bieber tweeted to over 17 million followers about his time in Manhattan: "That was one of the best things I have ever done. She was AWESOME. Feeling really inspired right now.''
