Osbourne was with the show for six seasons early in its run -- though her tenure never overlapped with creator Simon Cowell, who joined with Season 11. Previously, she said it was a "great" show for her to work on, but claimed issues with the network convinced her to leave.
"It is a boys club, it is and the boys take care of each other and the women are not paid as much as the men," she began, before noting how great the ratings were before Simon joined the show as a judge. "So when the show was doing 16 million, 14 million, Simon was never there."
She then called out the optics of another one of Cowell's shows, "The X Factor," which he judged in both the UK and the US. "Every time it came on, I think it was three seasons, it was different little girls. There was him, LA Reid and in between them was Demi Lovato and Britney Spears," she continued.
"Now, the guys looked like two high rollers in Vegas who picked up a couple of kids," said Osbourne. "They looked like dirty old men beside these two little girls and I was open, I told LA Reid and I told Simon, it's nothing I wouldn't say to their face. You look like two dirty old men, these are kids, they can't be judging other kids."
Sharon circled the convo back to "AGT," saying that, yes, it was a boys' club, but she also doesn't "begrudge anyone earning what they earned." That being said, she expressed frustration with getting an "American Airline ticket" while some of the men flew private.
"I get less because I'm me, I'm not in the club, I'm not one of the guys ... and because I tell them that they're dirty old men," Sharon added with a laugh.
The segment ended with Carrie reading NBC's statement on the matter. "We remain committed to ensuring a respectful workplace for all employees and take very seriously any questions about workplace culture," the joint statement with Cowell's company Syco and Fremantle read. “We are working with Ms. Union through her representatives to hear more about her concerns, following which we will take whatever next steps may be appropriate."
To that, Sharon added, "Stick together you guys. NBC can kiss my ass!"
The remark was met with thunderous applause from the studio audience.
