Simon Cowell has admitted he may have met his match in new X Factor USA judges Paulina Rubio and Kelly Rowland.
The mogul – who is now the only remaining male panellist on the US version of the show – revealed that he has been the victim of a few pranks at the hands of the mischievous pair – including a stunt involving bulls’ testicles.
“They made me eat bull’s balls and then Paulina ate them,” Simon confessed – although the Mexican singer admitted she wasn’t quite that daring.
“I didn’t swallow them!” she joked. “Simon wanted me to swallow them. I didn’t.”
The pair have replaced departing judges Britney Spears and LA Reid, joining fellow judge Demi Lovato who has stayed on for a second series.
But despite being outnumbered by the women Simon said he was very pleased with the current combination of judges.
“I kind of knew what I was getting myself into,”he admitted.
“I’ve done this for what 12 years now and it’s always, two guys, two girls. [But] you know what – I thought I can’t do this again – we have to do something different.”
He added: “We had this idea a few years ago to do me and three girls and it took a little while to get everyone to agree to it. And then you have got to get the right combination!’she added.
Viewers will be able to see the new line-up for themselves when The X Factor USA returns to screens on September 11.
