Kara DioGuardi is not on board with Howard Stern as a potential replacement for Simon Cowell on future seasons of American Idol.
"I don't really know if I can even speak on it," DioGuardi said of the Stern rumor during a press conference call Wednesday.
But then she did: "I don't know that [Stern] has a musical background," she mused. "I think that if you're gonna replace Simon, you have to have that background."
Nevertheless, Stern, 56, admitted Monday on his Sirius radio show that he was in talks to replace Cowell after the sharp-tongued Brit departs at the end of the current season.
"There's not a better job on the planet than judging that f---ing karaoke contest," the shock jock said. "It would be the best thing that happened to me...What a cush job -- $100 million for four months. Who wouldn't take that?"
DioGuardi, 39, had nicer things to say about the musical bonafides of Idol newcomer Ellen DeGeneres. "Ellen brings a sense of humor, of course, but also I think she knows more about music than we think she does," she explained.
"She had a really good handle on whether a contestant had potential," DioGuardi added. "She knew that something was off in the vocals or in their performance…I thought she delivered the message with kindness but also had criticism in there...she did an incredible job for her first time there."
What about rumors of DeGeneres butting heads with Cowell? "You have to take every rumor you hear about "American Idol" with a grain of salt," she recommended. "They usually aren't true."
