You Won’t Believe the Mistakes These Celebs Made in their Careers

14. Brian Dunkleman

If you do not recognize the name it is because of his big celebrity mistake. He was originally the co-host of American Idol with Ryan Seacrest. He left the show after only one season because he could not stand the way that the show treated contestants. He claimed the show was unnecessarily cruel. He did admit later that he would have stayed if he had known what a success the show would be.
