Paula Abdul has known new American Idol judge Kara DioGuardi since 1999.

Now, the somewhat insane singer tells Perez Hilton that she can't wait to work alongside Kara, despite rumors claiming she's concerned over the addition of a fourth panelist.

"I've been talking about her for years," Abdul said. "I hope the audience gets excited and accepts it. Sometimes its been hard when we've had four judges in the past. They always wanted four judges since the beginning. It'll be good to have two girls, and two guys. Kara's like a sister to me."
