Years of modeling and TV appearances taught Kristanna Loken the importance of staying in shape—but she was in for the workout of her life with her breakout role in Terminator 3: Rise of the Machines (2003). The blonde, B-cupped beauty spent countless hours getting sweaty in the gym, gearing up for her motherboard-mangling nude scene in T3. The Norwegian-bred babe managed to pack fifteen pounds of toned, tanned muscle onto her droolworthy five-foot-eleven-inch frame and showed every inch in a "birthing" scene that will have you saying "Hasta la vista" to your pants. Off-camera, Kristanna came out as a pulsatingly proud bisexual when she publicly sucked face with pop star Pink and engaged in a lesbian relationship with tough girl Michelle Rodriguez. Although she has since married a man, smokin' Ms. Loken's graphic Sapphism on season four of Showtime's The L Word will forever stand (erect) as a girl-girl cream-dream come true for the ages.
