Randy Jackson Says Replacing Simon Cowell Will Be 'Tough'

'I'm just gonna miss sitting next to him, learning from him,' Jackson says of departing 'American Idol' judge.

Simon Cowell is singing his swan song as one of the founding judges on "American Idol," and fellow original judge Randy Jackson said he will miss the Brit, even if he can be a grouch sometimes.

"Listen, he's my best friend ... one of my best friends in the world," Jackson told MTV News last week at the season finale of "America's Best Dance Crew," which Jackson executive-produces. "The guy is über smart. He looks at the whole picture. He looks at life on the show in a way no one else looks [at it]. I love him. I'm just gonna miss sitting next to him, learning from him."

The show already lost Paula Abdul last year and added Kara DioGuardi and Ellen DeGeneres over the past two seasons. But it when it comes to replacing Simon, Jackson said there are no real requirements.

"I don't think you can replace him," Jackson said. "I think you move with somebody different in that seat. It's a tough thing. We've been talking about it. We'll see where we end up."

Jackson also said there aren't any real front-runners at the moment, even though Howard Stern and Perez Hilton have tossed their hats in the ring.
