Ellen DeGeneres admits her biggest mistake ever.

As the young people’s Oprah and the goddess of TV, we thought Ellen DeGeneres could do know wrong when put in front of the camera. But when it comes to her career, DeGeneres says she recently made one really bad decision. Don’t worry Ellen, we’ve all been there.

The year the 57-year-old became a judge on American Idol for a short stint. Yet she has since admitted that it was one of her biggest career regrets.

"That's one of the worst decisions I've made," she told The Howard Stern radio show.

The American TV show host admitted that despite being a huge fan of American Idol, it didn't necessarily make her a good judge. The problem was, DeGeneres found it really hard giving her honest opinion to vulnerable contestants.

"As a fan of the show… I'm like everybody else at home, so I thought I'm gonna represent those people at home that have opinions," she told the radio show. "But then I just thought, like Howard says, I can't break this person's heart. Let somebody else do that."

DeGeneres was only a judge for a few months before being replaced by former judge, Paula Abdul. "It didn't feel like the right fit for me," DeGeneres admitted.

Everyone is enjoying having Ellen back on their screens in season 13 of her talk show. And we're loving the new segment she has introduced called Ellen's 7-second Mood Booster.
