The actor said pointedly that all of the incidents occurred before he was cast on "7th Heaven" and was emphatic that absolutely nothing inappropriate or illegal ever occurred with anyone from the cast of the show. He also discussed former cast member Jessica Biel and remarks he made about a racy photo shoot she did for Gear magazine when she was 17-years-old.  "I wasn't judging her at all.  Jessie is one of the great people I've ever known. And she just felt that she had been taken advantage of."
