According to TMZ.com, the star, real name Tila Nguyen, filed for an injunction to stop the release of the explicit video, made during a holiday with a boyfriend more than seven years ago.
Her lawyer claimed the tape is an invasion of her privacy and a misappropriation of her image.
But a Los Angeles County Superior Court judge rejected the argument on Thursday (07Oct10), noting “Tila exploits her sexuality”.
The judge also ruled that there wasn’t enough evidence to issue a restraining order against the star’s ex, whose name has not been released.
Tila rose to fame as a popular internet pin-up on MySpace.com, and has since become known as the bisexual star of U.S. reality dating show A Shot At Love.
