And they were told it was true.” Woods has remained silent since the reports first broke, but Thompson tweeted, “FAKE NEWS” before deleting his post. Reps for Kardashian and Thompson did not return PEOPLE’s requests for comment. Woods’ rep had no comment. It’s not the Cleveland Cavaliers player’s first cheating scandal, either. Last April, videos leaked of Thompson getting close to other women just days before Kardashian gave birth to their daughter True.
