Country star Taylor Swift debuted her song "Ronan" on Stand Up 2 Cancer 2012 telethon last week. Taylor Swift had heard about 3-year-old Ronan, who was diagnosed with Stage 4 neuroblastoma in August 2010, when his mother, Maya Thompson, started a blog to document his difficult journey. Thompson had no idea back then that one of her readers was going to be Taylor Swift -- and that Swift would one day turn the words on that blog, Rockstar Ronan, into a song.

Maya Thompson first met Taylor Swift last October, when Taylor invited her to a concert. Taylor continued to read "Rockstar Ronan" and months later, she left Thompson a voicemail.

Here's what the Huffington Post reported today:

On the blog, Thompson wrote about the moment she heard that message, starting with “Hey Maya, it’s Taylor Swift...,” and what happened when Thompson called Swift back -- "tears started pouring down my cheeks." She was completely overwhelmed with emotion, finding out that Swift had not only written the song, but would be performing it at the telethon.

This afternoon, Maya Thompson got to respond to the Taylor Swift song about her son Ronan with a local TV news station in Phoenix. Watch this touching video - and get ready with the tissues!
