The outspoken rock matriarch has returned to the ITV talent show alongside Simon Cowell, Louis Walsh and Nicole Scherzinger and it seems like we're in for a rather explosive series.
A source told The Sun: "Sharon's showing no mercy this year. She's had contestants, who have queued up for 16 hours to audition, in pieces… It's safe to say the bitch is back."
Sharon, meanwhile, told the newspaper she would never hurt someone's feelings on purpose, but her job is to say no to those who have no chance of making it in the music industry.
"I'm a mum and a grandma, I don't want to intentionally hurt anyone who comes to audition but sometimes you have to say no," she explained.
Sharon, 63, was an original judge on X Factor, but left at the end of series four. She returned for the show's tenth series in 2013, and then confirmed she would return for the now-filming 13th series.
She lives in the US where she's a panellist on The Talk, which is very similar to our Loose Women. She's also judged on America's Got Talent.
It is all change for this year's X Factor as the only judge returning from last series is Simon Cowell. Rita Ora, Cheryl Fernandez-Versini and Nick Grimshaw all quit.
As well as a new-look judging panel (well, a new judging panel for series 13 comprised of former judges), we'll see original host Dermot O'Leary returning after a one-year hiatus. Last year's presenters, Caroline Flack and Olly Murs, both stepped down after one series.
We'll also see the return of small intimate audition rooms, where hopefuls will have to impress the majority of the judging panel if they want to proceed to arena auditions, boot camp and the live shows.
X factor returns to ITV later this year.
