Britain"s Got Talent 2012: Alesha Dixon refuses to let Carmen Electra steal her thunder in eye-watering dress

A Baywatch babe ain't got nothing on me! Alesha Dixon refuses to let Carmen Electra steal her thunder in extremely low-cut dress

Reality TV judges usually wait until the live shows before hogging headlines in the fashion stakes.

But Alesha Dixon is wasting no time, pulling out all the stops at the Britain's Got Talent auditions.

The former Strictly Come Dancing panellist left onlookers open-mouthed as she ignored the recent snowfall to pose minus her coat at London's Hammersmith Apollo in a ridiculously low-cut dress.

Adrenaline obviously kept Alesha warm, as she shrugged off zero degree temperatures with a grin.

The 33-year-old squeezed herself into
the eye-watering frock to show a generous portion of cleavage, with the
white creation detailed with pink, black and yellow trim.

She completed the look with dark
curls around her shoulders, silver eyeshadow and what appeared to be a
pair of Christian Louboutin heels with the trademark red sole.

And it seems Alesha may have tactically chosen the outfit, as she was competing with a new rival.

Carmen Electra joined the panel today as she will be filling in for Amanda Holden.

Holden is currently having two weeks off after giving birth to second daughter Hollie Rose.

The former Baywatch actress joins Dixon, Simon Cowell and David Walliams.

An insider told the Daily Mirror:
'Simon took a fancy to Carmen and decided to fly her over. She looks
great and is very opinionated, but there is a concern from some of the
BGT production crew that she will not be the most familiar face to all
the viewers.'

It is believed Carmen, who previously
guest-judged on US talent show So You Think You Can Dance, will stand
in for Amanda until her return on Saturday for the Edinburgh auditions.

However, Alesha implied the US beauty was only on duty for one day, tweeting: 'Carmen Electra is the guest judge today 🙂 xxx'

She also revealed she is missing Amanda, as 'the boys are constantly winding me up!'

Meanwhile, Alesha has another reason to stand out today, in a bid to silence Kelly Brook.

The glamour model, who initially
joined series three of BGT before being axed after just a few days, says
Alesha made a 'mistake' quitting 'classy' Strictly for a 'circus'.

Kelly told Fabulous magazine: 'I wish Alesha all the best – it’s a fantastic opportunity.

'But I thought she was great on
Strictly and, personally, if I’d been a Strictly judge there’s nothing
that would have taken me from that job.

'Strictly is the most fantastic, lovely show with a very loyal following and it’s… classy.'

She added: 'The whole thing (BGT) is a circus and I don’t want my life to be like that.

'I’ve got enough drama in my life without having to deal with Simon Cowell’s as well.'
