Olivia Wilde must be the next hottest celebrity at present with her role as the leading lady in “Tron” alongside Sam Flynn. She had been guesting in two TV shows and she showed off her hotness that could knock all the boys down.  She showed up in Jimmy Kemmel in a short black dress, while she danced her booty in Ellen in a short blue chiffon dress. And wow, both dresses emphasized those gorgeous and long legs. All girls are dying to have those legs and boys are staring at them. Olivia Wilde sure spells hotness all over her.
