From YouTube to iTunes to national television.

Austin teenager Molly Kate Kestner's song "His Daughter," which went viral shortly after she posted it online last month, is now available through iTunes. Kestner, 18, announced the news on her Facebook page and on Twitter:

The Austin Daily Herald has also reported that she will be on "Good Morning America" on May 14.

Those are just a couple of the opportunities that have popped up for Kestner since she became a YouTube sensation. Her video of "His Daughter" has been viewed more than 6 million times.

The Daily Herald reports that she has been fielding offers from record companies, and wants to use any money she makes from iTunes to pay for college and to help end human trafficking. She plans to attend North Central University in Minneapolis.

Kestner shot the video at home Easter Sunday and shared it on Facebook. The next day she posted it on YouTube, and friend requests started rolling in. Its popularity exploded when social media celebrity George Takei shared the recording.

Since then, Kestner has been posting more videos (some original songs, some covers) on YouTube and Facebook. KAAL-TV reports she also sang the national anthem at a recent Minnesota Lynx game.
