Natalia Kills
Live talent shows require a lot of composure on the judge's end. New Zealand's version of "The X Factor" features a panel with Natalia Kills in the judge's chair. She took the meaning of "constructive criticism" to a whole new level when she completely roasted one singer. She called 2015 contestant Joe Irvine "a laughing stock" and accused him of ripping off her own husband, Willy Moon. Kills and Moon were later fired from the show.
