27. Olivia Munn
Biggest accomplishment this year: Co-starring in the upcoming second season of HBO's The Newsroom
Olivia Munn has been the biggest breakout star of HBO's The Newsroom, a slightly self-righteous look at the dynamics of a national news broadcast. In addition to her work on the show, Munn also had a three-episode stint this past season on New Girl as Nick's new stripper girlfriend. After two consecutive years finishing at No. 2 in the Maxim Hot 100 list, Munn plummeted to No. 28 this year; somehow, we think she'll get over it. She's also well-known for her devotion to animals and PETA, this year lending her face to a campaign against cruelty on Chinese fur farms.
