Each audition is another opportunity to show off another show-stopping look and on Tuesday Amanda Holden and Alesha Dixon made a bright effort to get noticed at the Britain's Got Talent auditions.

Both female judges stepped out at the London Palladium wearing eye-catching ensembles and the pair clearly hadn't called ahead to co-coordinated their outfits.

Amanda, 41, wore a neon melon italia power stretch dress that boasted a white reflective panel down the front, adding optical illusion detail.

Amanda arrived in great spirits and seems to have put Sunday's altercation with Simon Cowell firmly behind her.

The music mogul made a quip about her failed marriage to Les Dennis, joking that was how she found fame and the mother-of-two was not left pleased.

Amanda may well have wished she had revealed Simon's secrets in her upcoming book, but the actress has previously admitted that she hadn't spilled the beans in the autobiography.

Speaking to the Metro she said: '‘No one will be worried but there will be lots of juicy revelations,’

‘I’ll have to wait until Simon’s dead to come out with the truth!’
She added: ‘It’s an honest book but also a book that every age can read. It’s a book that I want my daughters to be proud of.'

But Simon might have had other things on his mind at the auditions as he showed up with his stunning make-up artist in tow, who looks strikingly similar to ex-fiancee Mezhgan Hussainy.
