Paula Abdul has told “OK Weekly” that adding a fourth judge — Kara DioGuardi — to the “American Idol” panel this year was a mistake. She explains, “It takes up so much time for each of us to give our opinion that it slows down the pace of the show.” Of course the great reviews that DioGuardi is getting have nothing to do with this insight from Abdul, do they? According to Abdul, “Kara and I have known each other for years and we get along great.” All this talk may be Abdul’s way of easing herself out of the show with her dignity somewhat intact. As she says, “It is the last season of my contract, and I have so many other things I want to do.”
