Toronto's Madison Tevlin is becoming a YouTube star

A young singer from Toronto has become a bona fide YouTube star.

Madison Tevlin is 13 years old. She has Down syndrome and she wants everyone to know that it doesn't define her.

"I always feel confident in myself, a lot...when I sing, I feel so confident in myself," she told CBC News in an interview.

Last summer, Tevlin covered "All of Me," a John Legend song. The recording was posted to YouTube and has now been viewed more than three million times.

"Oh my God, this is becoming crazy, it's going viral," Tevlin said.
