Every star has some career regrets, but it seems like no one is more passionate about hating something than Kelly Clarkson.
What did the American Idol winner do that haunts her every single day? She filmed From Justin to Kelly alongside fellow alum Justin Guarini. She regrets the project so much, in fact, that she has joked with her nanny that she would fire her if she ever showed the movie to her daughter River Rose.
When asked by Rolling Stone if she would "burn all the existing copies" of it, she responded, "No, I think I would have to own it first. But that is something I will look into."
She added, "I have a little joke with our nanny, because she told me she loves that movie. She was like, 'My roommate and I used to watch it all the time! I'm totally going to show your daughter From Justin to Kelly.' I'm like, 'I will fire you.'"
