Best known as a regular on “House, M.D.,” the 26-year-old Olivia Wilde is starring in “Tron: Legacy.” Maxim has ranked her on their “Hot 100” list three times, including the #1 spot in 2009.

She was born in New York City but has dual citizenship in the United States and Ireland, where she attended acting school. She’s a natural blonde, but has said she feels more like a brunette and has found that people treat her differently.

She was born Olivia Jane Cockburn, and (wisely) took Wilde as her stage name. She eloped with her husband, who is the son of an Italian prince, when she was only 18.
