This just in from tmz.com It’s one and done for Ellen DeGeneres — she’s leaving “American Idol” after her first season as a judge on the show … claiming it wasn’t the “right fit.”

Ellen just tweeted, “Dim the lights … I’ve voted myself off American Idol.”

Ellen claims she came to her decision, “a couple months ago” — and admits, “It was hard for me to judge people and sometimes hurt their feelings.”

She concludes, “I am very grateful for the year I had. I am a huge fan of the show and will continue to be.” It seems that everyone is leaving Americal Idol. I wonder who the next judges will be.
