Roman Polanski's victim, Samantha Geimer, is backing the film director's campaign to have criminal proceedings dropped against him.
Reportedly, she did not want Polanski jailed if he returned to the United States from his European exile.
Geimer (45) is a married mother-of-three and has moved to Hawaii to escape attention.
In January, Geimer filed a formal request that Los Angeles prosecutors drop the charges against him.
Geimer said she wanted to stop reliving the horror of the assault.
Polanski was arrested in the US in 1977 and charged with giving drugs and alcohol to a 13-year-old girl and having unlawful sex with her at a photographic shoot at the Hollywood home of Jack Nicholson, the American actor.
He admitted unlawful sexual intercourse as part of a plea bargain with prosecutors but fled to France after it emerged that the judge was likely to jail him beyond the 42 days set out for his evaluation.
