Mila Kunis is hotter than ever. The "Friends With Benefits" actress rose to No. 3 on Maxim 's Hot 100 List this year after coming in fifth place in 2011. According to the men's magazine, which considers its picks "the definitive list" of the world's most beautiful women, "Ever since she locked lips with Natalie Portman in 'Black Swan,' our appreciation for this brunette stunner has transformed into a near obsession." And Ashton Kutcher would probably agree. Last month, he was spotted on a bunch of dates with his former "That '70s Show" co-star, although they claim to be just friends. Model Bar Refaeli, 26, who appeared on the cover of the Sports Illustrated Swimsuit Issue in 2009, took the top spot on Maxim 's list.
