The talent show judge appeared on the latest instalment of This Morning to discuss the latest series of the ITV programme, explaining a certain act proved too lewd for the music mogul.
When probed by hosts Eamonn Holmes and Rochelle Humes about the act, she responded: “Well, it’s hard to explain to the audience…”
Passing over the baton to Rochelle, the This Morning host described the sketch – “an artist who paints with his nether regions”.
Having been involved in BGT since 2012, the mum-of-two admitted “it takes a lot” for the judges – Simon Cowell, Amanda Holden and David Walliams – to be “shocked”.
But the nude painter was a step too far for Simon who soon threw in the towel when the artist exposed his manhood and started work on his masterpiece.
“Simon walked out,” she proclaimed.
“We went on stage to see it up close – and just make sure it was actually happening.”
Despite the act’s best efforts, the former Mis-Teeq singer confessed the skit wouldn’t be suitable for the Royal Variety Performance.
“I don’t know if they can show it on the telly, she exclaimed.
“We can’t put that in front of the Royal Family!”
And Rochelle, along with This Morning, seems to be familiar with the painter in question as he’s appeared on the show a handful of times.
“We’ve had him on here,” she said.
“He’s painted Holly and Phill!”
This Morning continues on ITV at 10:30am.
