Roseanne Barr, Megyn Kelly Among Celebrities Who Fell From Grace in 2018

The “Roseanne” reboot catapulted Roseanne Barr from has-been to triumph this year, but it all came crashing down after the star posted a tweet comparing former top Obama advisor Valerie Jarrett to a character from “Planet of the Apes." It resulted in the cancellation of her top-rated show. “I made a mistake,” she told Fox News host Sean Hannity. “Obviously it cost me everything.” Megyn Kelly also fell from grace this year after suggesting that wearing blackface for Halloween was acceptable.
