Caitlyn Jenner might be one of the most well known figures in the transgender community, but Kardashian biographer Ian Halperin says the road has been very challenging for the reality star. Halperin, who wrote "Kardashian Dynasty: The Controversial Rise of America's Royal Family," said that multiple sources told him that Jenner has been miserable since her transition and is thinking about de-transitioning back to a man. Now a Jenner rep has told The Daily News the report is "Not worth commenting on such an idiotic report."
