She is of Norwegian ancestry and grew up on her parents organic fruit farm. She has a sister, Tanya. As a child, Kristanna Loken was involved in singing, acting and dancing. She also loved to horseback ride.
With her mothers encouragement, Kristanna entered the 1994 Elite Model Look and placed 3rd runner up. She began acting with parts in As The World Turns, Philly, Unhappily Ever After, Boy Meets World, and Mortal Kombat: Conquest, but it was her role as the cyborg T-X in Terminator 3: Rise of the Machines that made her a star.
Of her physique, Kristanna Loken said, Im almost six feet tall and have a deep voice. People never knew how to cast me (askmen.com). She added in another interview, I wasnt always comfortable being 5 11 and having an athletic build. Actually, until [T3], I wasnt. Im finally now comfortable in my body. I think that feeling strong is really an empowering place to be, especially for women. Knowing they can handle themselves in certain situations, thats invaluable (movies.about.com).
Other roles followed, including parts in Die Nibelungen, BloodRayne, In the Name of the King, The L Word and Painkiller Jane.
She was most recently seen on the series Burn Notice.
Kristanna Loken came out as being bisexual. She told Curve in 2006, I have dated and have had sex with men and women and have to say that the relationships I have had with certain women have been much more fulfilling, sexually and emotionally, than those with certain men. I connect with an aura, an energy. And if the person with whom I connect happens to be a female, thats just the way it is. Thats what makes my wheels turn.
Kristanna Loken told After Ellen, I think for me, really, everybody is so quick to attach a label. If youre with a man, now youre considered straight. If Im with a woman, Im a lesbian. I think labels are very confining and restrictive, and I think people should just be able to be happy with the person they choose, regardless of the gender and the title.
Kristanna added about her career, Ive worked very hard not to be viewed [as the blonde bombshell] because I think it could have been a very easy route to go downI dont want to turn 40 and be put out to pasture. I want to have a long career.
Kristanna Loken was engaged to her Painkiller Jane co-star Noah Danby. They were married in 2008, but they have since separated and Kristanna has stated she is now in a relationship with a woman.
