Eek! Britain's Got Talent 2012 judges blast rubbish guest judge Carmen Electra!

Carmen Electra (Britain's Got Talent 2012)

Bitchy Britain's Got Talent judges Alesha Dixon and Amanda Holden ripped into the show's guest judge Carmen Electra last night.

Speaking at the show's press launch, Alesha revealed how she and fellow new judge David Walliams didn't get on with the Baywatch star when she stepped in for Amanda in London.

Asked why he picked the busty blonde beauty to join the show, Simon explained: "She has got the best set of… teeth I've ever seen!

"You know what, I met Carmen in America, I really, really liked her. I like the idea of bringing and American over because she's seen the show from an American perspective, which actually makes it quite funny."

But when it came to whether or not Amanda should be worried about being replaced, the mum-of-two interrupted: "One minute, I'm going to answer that. No, I don't think I've got anything to worry about!"

West End actress Amanda also attacked Carmen's career, questioning Simon for referring to her as an actress.

Amanda moaned: "Is she [an actress]? She's only been in Baywtach and that was a stretch for her!"

And even boss Simon conceded that the American guest didn't get on well with the other panel members, admitting: "She didn't get on great with David and Alesha."

Alesha insisted: "But we tried," before revealing how Carmen didn't bother to get to know their names.

"Even though they were in big bold letters above us," the former Strictly judge added.

The show's team expressed concern over the strange appointment back in February, when it was first announced that the 40-year-old ex-Playboy model would be temporarily joining the panel.

An unsure Alesha said of her new fellow judge at the time: “Carmen is interesting… it’s nice to have another female on the panel.”

But she defended the US star's poor reaction from the live crowd at the auditions, saying: “It’s difficult to come from another country and understand British humour.”

Britain’s Got More Talent host Stephen Mulhern revealed: “They [the audience] nearly turned on her, the audience were going for her. It’s worrying.”

Meanwhile, Amanda explained her decision to return to the show so soon after giving birth, insisting that BGT is not work!

She said: "I don't consider it work. I think digging the roads is work, or working nine-to-five… I think sitting at a desk and pressing a buzzer for a day is a treat.

"I needed something, so that's why I came back. I had the best fun."

Amanda quipped: I was desperate to see Simon, and I saw him when I flat lined actually!"

Britain's Got Talent 2012 will kick off tomorrow at 8PM on ITV1, with footage of Carmen's stint as a guest included in the first show.
