“The Masked Singer” has been a massive left-field hit, but one star who wasn’t surprised the show worked was Jenny McCarthy.

“My agents will get so mad at me, but I have to tell the truth,” McCarthy confided in us on a break from her SiriusXM show at the Super Bowl. “They were like, ‘Listen, there’s a couple shows you have offers for, but this one is a definite pass.’ And I said, ‘Well let me see it!’ And they’re like, ‘You’re going to hate it.’

“So they sent it to me, and I watched it — the Korean version — and I said, ‘This checks all the boxes, this is going to work.’ I thought, ‘It’s weird enough and different that it gets people’s attention. It’s got celebrities, which people f–king love. And it’s got the mystery, so you’re brain’s trying to figure out who the people are. And you can watch it with your kids.’

“When it hit, they called me and were like, ‘You’re the only one who believed in this show.’ Every single person outside of the network thought that this was the worst thing that could possible come on television.”

McCarthy told us it shot for just nine days over the summer. The Korean import on FOX also stars host Nick Cannon and judges Robin Thicke, Nicole Scherzinger and Ken Jeong.
