Knoxville Takes Polygraph Test Over Simpson Rumours

Jessica Simpson's relationship with Johnny Knoxville came under scrutiny again last week (03AUG05), when the former JACKASS star was surprised with an on-air polygraph test during a radio interview.

Simpson and Knoxville, who are both happily married to other people, have long been fighting off rumours that they embarked on a romance while shooting their new movie The Dukes of Hazzard.

And Knoxville was stunned when he arrived for an interview with US shock jock Howard Stern and was asked to take a lie detector test, where the questions included if he had sex with Simpson, if they'd ever tongue-kissed and if he ever thought about the singer while "pleasuring himself".

After answering no to all questions, the polygraph indicated that he did not have sex with Simpson, but that he did kiss her and pictured her while pleasuring himself.

Knoxville says, "I don't put any faith in that test."

His representative adds, "The lie detector test was all in good fun. Johnny thought it was hilarious."
