When Toby Keith's daughter, Krystal, started to express interest in a music career several years ago, the country superstar had just one rule for his little girl: she had to finish college first. Well, Krystal graduates from the University of Oklahoma this month, so expect to hear new music from her soon!

Country Music Tattle Tale reports that Krystal will start working on an album next year. Her face and voice might already seem familiar, as she recorded a duet with her dad, 'Mockingbird,' on his 'Greatest Hits 2' album. The two sang it together on the 2004 CMA Awards. Watch their performance here.
