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.
Natalie Maines
Natalie Maines, the singer for The Dixie Chicks, has a hard time separating politics from her art. Not saying she has to, but one particular remark didn't go over well with fans. She made some comments about President Bush, and radio stations stopped playing her music and wanted to pull her from streaming platforms. She didn't care what her southern conservative fans thought and is one of music's most badass women.
