This is Maxim’s 10th anniversary of the Hot 100 list, which showcases athletes, actresses, reality show stars, models… and even the First Lady.

Maxim editor Joe Levy commented Olivia Wilde taking the #1 slot, saying, “Olivia Wilde has been the sexiest woman on television since she heated up ‘The OC’ five years ago. She’s smart, she’s beautiful, and she has dual citizenship in the US and Ireland — what more can a man ask for?”

Olivia Wilde plays Thirteen on House, but has also had roles on The O.C. and The Black Donnellys. Wilde will next be seen in the Jack Black comedy “Year One.” Check out these Olivia Wilde pics:
