The 34-year-old actress (her birthday is September 28, 1987) was born in Texas to a film and music producer mother and a father who owned several convenience stores across Texas. From a very young age, Hilary and her sister Haylie showed interest in the performing arts. One of the biggest sources of inspiration for their interest in performance, even talks of Hollywood fame, came from watching their mother’s work.
Starting from when they were as young as three years old, the Duff sisters enrolled in dance classes, singing lessons, and tried out for local theater shows. Hilary later reflected that one of the reasons she wanted to enroll in all of these activities was that her sister was doing it.
