Real name and early life

Biography.com and Britannica identify her birth name as Demetria Gene Guynes, born November 11, 1962, in Roswell, New Mexico (Biography.com; Britannica). She was raised by her mother Virginia and stepfather Danny Guynes, moved frequently as a child, settled in Los Angeles as a teen, left high school at 16, and worked as a debt collector and model before acting. In 1981 she married musician Freddy Moore and adopted Moore as her professional surname; “Demi” is the familiar short form of Demetria.

Career highlights

Moore played Jackie Templeton on General Hospital, joined the Brat Pack via St. Elmo’s Fire (1985), and became a 1990s box-office lead with Ghost, A Few Good Men, Indecent Proposal, and Disclosure. She was briefly among the highest-paid actresses in Hollywood (Striptease), starred in G.I. Jane, produced the Austin Powers films, and later appeared in Margin Call, Feud: Capote vs. The Swans, and Coralie Fargeat’s The Substance (2024), winning a Golden Globe for Best Actress in a Musical or Comedy. She has three daughters with Bruce Willis and published the memoir Inside Out (2019). Earlier tabloid fame around her marriages to Bruce Willis and Ashton Kutcher often overshadowed craft; later roles and the Globe for The Substance reframed her as a dramatic lead again. Billing stayed Demi Moore; the documented birth name is Demetria Gene Guynes.
