A tall, natural redhead blessed with girl-next-door good looks, actress Laura Prepon endeared herself to audiences as the strong-willed Donna Pinciotti for eight seasons on the hit sitcom "That '70s Show" (Fox, 1998-2006). Launched to star status along with her young co-stars, who included the likes of Mila Kunis and Ashton Kutcher, she suddenly found herself ranked as one of the world's sexiest woman in men's magazines like <i>Maxim</i> and appearing in feature comedies like "Slackers" (2002). After "That '70s Show" completed its run, a gamble on a second series, "October Road" (ABC, 2007-08), unfortunately failed to pay long-term dividends. In the meantime, Prepon kept busy with frequent guest spots on such popular sitcoms as "How I Met Your Mother" (CBS, 2005- ) until another shot at a regular gig - this time as the show's star - came along in the form of "Are You There, Chelsea?" (NBC, 2012- ). Talented, ambitious and with an eye on career longevity, Prepon had done an admirable job of positioning herself as a dependable and versatile television presence.
