Miley was somewhat famous at birth, thanks to her "Achy Breaky Heart" dad, Billy Ray Cyrus, who was a country music heartthrob ... despite his mullet. Her pop tells the story that his 8-year-old daughter declared she wanted to be an actress after watching a production of "Mamma Mia!" in Toronto, the city where he shot his TV show, "Doc." The little girl reportedly grabbed his arm during the first act and said, "This is what I want to do, daddy." Ron Galella, Ltd./Ron Galella/WireImage.com - October 8, 1994
