Simon Cowell and Carmen Electra all over each other at Britain's Got Talent auditions!

Carmen Electra on BGTSimon Cowell and Carmen Electra were apparently 'inseperable' as they shamlessly flirted with each other at the Britain's Got Talent London auditions!

According to The Sun, David Walliams and Alesha Dixon were left 'infuriated' by their fellow judges as they held hands, shared private jokes and even stroked each others' backs and arms in front of the audience.

Carmen - who was standing in for Amanda Holden - even had to apologise to one act for ignoring them as Simon teased her.

An onlooker at the Hammersmith Apollo said: "Everyone was stunned when Carmen turned up, but it's become increasingly obvious why Simon booked Carmen. As Tuesday's auditions wore on, they were inseparable.

"It was embarrassing the way they were all over each other. They were play-hitting each other like awkward teenagers."

The American beauty also sided with Simon in her opinions, with the source adding: "If Alesha and David liked it, Carmen and Simon didn't and vice versa."

Meanwhile, David apparently snapped at her after she told one performer: "I was kind of bored. I was distracted by [Simon's] shirt, the colour, the texture... "

The funnyman retorted: "Stop looking at him, look at the act on stage."

Carmen was no doubt glad to have Simon's support after the crowd reacted negatively to her appearance, by booing and chanting 'Bring Amanda back!'
