One of the three finalists in Fox's hit Joe Millionaire is "tied up" in a controversy.

The blond bombshell Sarah Kozer has reportedly starred in dozens of bondage and fetish films under a pseudonym, The Smoking Gun Web site reported Wednesday.

Kozer, 29, has reportedly starred in such flicks as Novices in Knots and Hogtied, and a foot-fetish film, Dirty Soled Dolls.

On the latest episode of the reality series, Kozer got tipsy with faux millionaire Evan Marriott on their date at a winery. Marriott, who said he'd thought Kozer was a "goodie goodie" found her "wild side" after a few drinks: The duo was shown sneaking off into the woods near the castle where they were staying to share an intimate moment.

According to The Smoking Gun, Kozer was clothed in her movie appearances, which included being gagged and hog-tied in a cheerleader's uniform. She also ties up other characters.

Kozer is one of a trio of women still hoping to land Marriott in the Fox series. The show drew more than 20 million viewers on Monday, its biggest audience yet.

Fox wouldn't say if it knew about Kozer's past before casting her.

"We don't comment on the personal lives of the contestants," network spokesman Scott Grogin said.

There was no answer to a telephone call to Kozer's Los Angeles home on Wednesday. The Smoking Gun said she wouldn't comment when reached by its reporter.

Kozer's occupation is described as "sales and design" on the show's Web site. And there's no mention of her acting jobs, under the name Cindy Schubert, in her brief bio.

When asked, "What is the wildest thing you've ever done," she said there was a long list but picked backpacking in Morocco.

"Most of my 'wild' things involve adventure and romance," she said.
