Former Alaska Governor Sarah Palin was revealed as a contestant on "The Masked Singer" after she sang "Baby Got Back" in a bear costume. The celebrity judges on Wednesday night's episode of the popular game show were having a hard time figuring out who was rapping the Sir Mix-A-Lot hit, and thought maybe it was Christina Applegate or Tina Fey. Then host Nick Cannon told her to remove the mask, and it turned out to be Republican politician Sarah Palin. Palin called it the weirdest thing she's ever done, but said it was all about fun, and unity. Then she sang the 90s hit again, except without the mask.
