Avalanna Routh, or "Mrs. Bieber" as she likes to be called, was all dressed up for Valentine's Day as she described her dream date with teen heartthrob, Justin Bieber.

"He said 'I want you too'," Avalanna said. "He wants to be my husband."

Avalanna's story gained nation-wide attention after friends started a Facebook and Twitter campaign to get the six year-old girl -- who is fighting a rare form of brain cancer -- to meet the love of her life.

The hashtag "#Mrs. Bieber" even trended across the country on Twitter.

After Avalanna's story appeared on Boston NBC affiliate WHDH, her dream came true

Bieber flew Avalanna and her family to New York on Monday.

The two played Candy Land together -- Avalanna says Bieber won, but she didn't let him win.

The pair gave each other autographs and Bieber even let the amazing little girl style his world-famous hair.

"Move over Brangelina, Javalanna is here," said Avalanna's mother, Aileen Routh on Tuesday.

Bieber tweeted out right after their meeting, "That was one of the best things I have ever done. She was AWESOME! Feeling really inspired now! #Mrs. Bieber."

Avalanna's dream came true and now her mother hopes the focus switches to finding a cure for the disease.

"I think he's a great kid that took time out to do this, but remember cureATRT.org -- we need to fund a cure. We need to find a cure and we need to do it now," said Aileen Routh.

Avalanna was diagnosed when she was 9 months old.

"She's beaten all the odds. It's a very aggressive, rare disease, and she's been in treatment for 5.5 years," said Aileen Routh.

Avalanna is now focusing on her next round of treatments.

"Say lots of prayers," Avalanna said on Tuesday. "Say lots of prayers."
