Bar Refaeli, Olivia Munn and Mila Kunis topped Maxim's hot 100 list 2012, but there was one surprise addition to this year's list: Stephen Colbert. 

Ranking at number 69, Colbert made the all-female list ahead of Sofia Vergara, Michelle Dockery and Kellie Picker. 

Bar Refaeli took the number one spot on the list. I am shocked that among all these beautiful ladies, I'm No. 1, she told the magazine. Thank you so much for voting for me! I'm truly honored. This is a title I will never forget.

Refaeli, an Israeli model, started modeling when she was just 8-months, starring in a baby commercial. She has since won various beauty contests and featured in ELLE, Maxim and GQ. She is also Leonardo DiCaprio's ex. 

Actress Olivia Munn, a two-time Maxim cover girl, took the number two spot on this year's list. 

Mila Kunis, Katy Perry, Olivia Wilde, Jennifer Lawrence, Emma Stone, Megan Fox, Malin Akerman and Adrianne Palicki all made the top 10 of this year's list. 

Last year, Rosie Huntington-Whiteley from Transformers 3 topped the list, but this year she has dropped down to the number 11 spot. 

Natalie Portman and Cameron Diaz, who were in the top 10 of the list last year, did not even make it into the top 100 this year. 

Nina Dobrev from the Vampire Diaries features in the list for the first time with a debut at number 86 this year. 

Millions of votes were cast by Maxim readers and the full list will be published in the magazine's June issue.
