By the age of eight, Duff landed a role in the Houston Metropolitan Dance Company's production of The Nutcracker Suite.

Career

In addition to guest-starring roles on Chicago Hope, Boston Public, and Third Watch, Duff became a familiar face starting in late 2002 as Amy Saunders/Sanders on the children's television series, Lizzie McGuire, which her sister Hilary starred in as the title role. In 2004, Duff made a guest appearances on That's So Raven as Katina Jones. After making guest appearances on television, Duff received her first role in a feature film when she was cast as Summer Wheatley in Napoleon Dynamite. The film earned her first Teen Choice Award win. She continued making guest appearances, which include Joan of Arcadia and American Dreams. She also lent her voice talent to the Christmas animation film In Search of Santa which again, featured sister Hilary.

Following Material Girls, Duff appeared in various made-for-television or straight-to-DVD films including Nightmare, My Sexiest Year, Legacy, Backwoods, Love Takes Wing, Love Finds a Home and My Nanny's Secret.

Between 2008 and 2015, Duff appeared in various films and TV roles, including; Fear Island, Tug and Slightly Single in L.A.. She lent her voice to the animated film Foodfight!, but due to distribution issues, the film was delayed for years until it finally saw a release in 2012.

Personal life

In 2009, Duff stated, "I am a Christian, but I also don't really see myself as a religious person. I see myself as more of a spiritual person. There are a lot of things that I do agree with in Christianity and things that I don't agree with. I'm not a regular churchgoer, but I do think that I have my own beliefs that I feel strongly about."

In April 2014, Duff announced her engagement to Matt Rosenberg after one and a half year of dating and gave birth to their daughter, Ryan Ava Erhard, on May 11, 2015.
