Tanned, blonde and exceptionally pretty, Sara Jean Underwood is a no-brainer for the list of the hottest women of 2013. Her resume is almost a checklist of steps to become a hot woman — work at Hooters; wear bodypaint in Playboy college issue; become a Playmate; become Playmate of the Year (2007); host 'Attack of the Show!'; date Ryan Seacrest.

Underwood helped wrapped up the final 'Attack of the Show!' in January. She will probably spend 2013 making personal appearances, stopping by the occasional radio show and cavorting with other Playmates.
