Girls donate Justin Bieber tickets to sick seven-year-old girl

KELLER, TEXAS -- Seven-year-old Emma Routh is a huge Justin Bieber fan who happens to suffer from a rare blood disorder. Thanks to the some very unselfish girls, Routh gets to attend a Justin Bieber concert!

Routh's family could not afford tickets to Justin Bieber's concert in Dallas later this month -- but Routh is going to the show after all!

Dawson Beaty and a friend saw Emma's story on Facebook and made Emma's dreams come true.

"I wanted to go to the Justin Bieber concert, but she really wanted to go, so I let her have my Justin Bieber concert tickets," Beaty said.

The girls had never met before. Now, it's probably safe to say they're the best of Facebook friends!
