Who Is Diane Finnegan Kutcher?
Diane Finnegan Kutcher is an American woman from the Midwest. She is known to the world as the mother of actor Ashton Kutcher and his twin brother, Michael Kutcher. However, her life is much more than just her connection to her famous son. She spent many years working at Procter & Gamble, balancing a career and raising a family.

She comes from a background with Irish, German, and Czech roots. This heritage is a strong part of her family’s identity. Diane has lived most of her life in Iowa, far from the lights of Hollywood. She represents the values of a “heartland” family: hard work, humility, and a deep focus on her children.
A Family Built in Iowa
Diane’s family story begins in Cedar Rapids, Iowa. She was first married to Larry M. Kutcher, who worked in a factory. Together, they built a life and a home. They raised their children in a “relatively conservative” Catholic household, teaching them the values they grew up with.
This marriage gave Diane Finnegan Kutcher her three children. First came their daughter, Tausha Kutcher. A few years later, Diane gave birth to fraternal twin boys: Christopher Ashton (who the world knows as Ashton) and Michael. The family was complete, but their journey was not always easy.

Through all his fame, he never forgot his mom. In 2015, Ashton gave Diane Finnegan Kutcher the surprise of a lifetime. For Mother’s Day, he partnered with the home design company Houzz to completely renovate the basement of her Iowa home.
He said it was his way of saying “thank you” for all the sacrifices she made. The emotional surprise was filmed, and Diane’s tears of joy showed how much it meant to her.
