ABC's American Idol expos&#233 doesn't air until next Wednesday, but already Paula Abdul is going on the defensive. In a statement released to Access Hollywood and then passed on to TVGuide.com via an Access Hollywood publicist (phew!), a spokesperson for Abdul said, "Paula will not dignify the false statements made by [former contestant] Corey Clark with a response." Oddly enough, the rep then proceeded to dignify the so-called false statements made by Corey Clark with a response, insisting, "Mr. Clark is an admitted liar and opportunist who engages in unlawful activities. He is communicating lies about Paula Abdul in order to generate interest in a book deal." Abdul has also threatened ABC with a lawsuit if it moves ahead with the Primetime Live piece, in which Clark reportedly claims to have romanced the pint-size judge while he was a contestant on the show. Even more damaging, Abdul was allegedly sober during one of the encounters.
