Which actress played Remy Hadley, nicknamed Thirteen, in House M.D.?

Olivia Wilde played Remy Hadley, nicknamed Thirteen, in House M.D.

Remy Hadley becomes a member of House’s diagnostic team during the fourth season. The nickname “Thirteen” comes from her contestant number in House’s highly competitive hiring process, and it remains her best-known name within the hospital.

Wilde’s performance became central to several long-running stories involving Thirteen’s family history, relationships, and medical future. The character is bisexual, and the series explored that aspect of her identity as part of its broader character-driven storytelling.

Olivia Wilde later became widely known for films such as Tron: Legacy, Cowboys & Aliens, and Booksmart, which she also directed. Jennifer Morrison played Allison Cameron, while Anne Dudek played Amber Volakis and Amber Tamblyn played Martha Masters. Those performers are associated with other House M.D. doctors, not Thirteen.
