No. 38: Olivia Wilde — Hottest Women of 2013

Actress and model Olivia Wilde has quickly become a standard bearer of hotness and intelligence. Though she was every bit as beautiful on 'The O.C.,' it wasn't until Wilde's turn as 'Thirteen' on 'House,' opposite Hugh Laurie, that Wilde found fame. Truth: If all doctors looked like Wilde, guys would be sprinkling anthrax in their cereal. Wilde has since gone on to major films such as 'Tron: Legacy' and 'In Time.'

Wilde recently confirmed her engagement to comic actor Jason Sudeikis. She's featured in the upcoming films 'Rush,' 'Her' and 'The Incredible Burt Wonderstone,' all of which are due in theaters in 2013.
