One day after Fox announced that Ellen DeGeneres had signed on to be the fourth judge on American Idol, Paula Abdul has nothing but good things to say about her replacement.

"I think Ellen will b a gr8 judge on Idol," she Twittered Thursday. "She is wildly funny, talented and I wish her the best of luck!"

Abdul, who left the show in August after eight seasons, might even see a bit of her own personality in the comedian. After all, in an interview on Ryan Seacrest's KIIS-FM radio show early Thursday, DeGeneres stressed that she'll be an "honest" judge who will "bring compassion" to the show. She also mentioned that she'll do her best to keep fellow judge Simon Cowell in check.

"I'll tell him the same thing I tell him when he's on my show -- that he's mean," she said. "You can be constructive, and you can criticize someone in a way that's helpful and not mean-spirited."
