No. I don't think so.
i have heard that randy, Simon, kara, and possibly Katy perry and 'Avril lavigne' will be guest judging!!
i heard that it was paula Abdul but i am not quite sure yet. I guess we will find out tonight ! Go Giants !
season 9 as a guest judge
Yes, she was a guest judge on the previous season for auditions
That was her younger sister Ann Prentiss in the episode.
Allison Iraheta appeared as a contestant on season 8 of American Idol and finished the season in 4th place. She returned as a guest on the show in season 9.
there has to be some guest stars on that season finale
I heard a Vegas show is in the works. She has guest starred as a judge on a new lifetime show, and if you haven't heard, she will not be returning to American Idol. She has spoken of starting a talent competition show and was asked to be a judge on 'So You Think You Can Dance'. She has neither turned down the offer or accepted it. It is unclear what she is doing at this EXACT moment, and we can only go with what we see in the headlines. (or her twitter). For more updates on what Paula is up to....add her on facebook or twitter. Hope this helps!

Taylor Swift has never performed on American Idol, and considering there is only one season left, it's unlikely she ever will.
