Two weeks ago I told you about 8-year-old Ryan who wrote a letter to Santa asking him to make the kids at school stop bullying his sister. 

Instead of writing a list of toys he wanted, Ryan wrote, “Kid at school are still picking on Amber and its not fair because she doesn’t do anything to them. I prayed that they will stop but god is busy and needs your help.” He also asked for his sister to be able to meet her musical idols. "Can you ask Big Time Rush to come to Amber's birthday party? It will make her so happy,” he wrote.

Well, part of Ryan’s wish for his sister came true. On Good Morning America last week, Amber was serenaded by Big Time Rush.

The twins’ mom, Karen posted the letter to her Facebook page and it went viral and that’s when Good Morning America saw it and decided to grant one of Ryan’s requests with the Big Time Rush performance.

The show also gave the family VIP passes to the Big Time Rush concert this past weekend in New York City.
