AUSTIN — Austin High School senior Molly Kate Kestner has been featured on dozens of media outlets since her original song, “His Daughter,” went viral after she posted it to YouTube April 20. On Tuesday, Kestner made her national television debut as she appeared on ABC’s “World News With Diane Sawyer.”

“A star is born, a video we’ve watched, all of you sharing all day, 6 million views for a teenage girl and a song played on an out-of-tune piano,” Sawyer said to introduce a two-minute piece on Kestner.

ABC News also called Kestner a “Cinderella still in the middle of her dance” and a “new sensation.”

“It is a voice that has captured the world,” ABC’s Paula Faris said.

Kestner was slated to appear on “Good Morning America” this morning.

“His Daughter” is now available on iTunes for $1.29, along with an acoustic version for the same price.

The YouTube version, recorded by Kestner on an iPhone, was viewed more than 850,000 times within the first two weeks. It’s now been viewed more than 6.1 million times.

Despite her newfound fame, Kestner said last week she’s taking things slow as offers roll in. She’s still set to attend North Central University in Minneapolis this fall.

“I’m still trying to focus on my senior year,” Kestner said.
