This Las Vegas-born bombshell got her start with a string of guest appearances as Kirsten's stripper sister on The O.C. and quickly segued to her own series, North Shore, which made good use of her bikini-ready body. While the show was canceled in its freshmen year, Amanda Righetti returned to primetime the very next season in the equally short-lived Reunion. But despite her relatively limited TV time, the sultry-eyed brunette (or blonde, depending on what show she's on) is a favorite pinup of men's magazines.
