BGT judge Amanda Holden threw her microphone down after her rendition of Let It Go didn't prove a hit with the crowd

With an audience of hundreds watching you (not to mention Ant & Dec eyeing you from the sidelines), we imagine that getting up and performing on the Britain’s Got Talent stage is one of the most nerve-wracking things you can do.

Just ask Amanda Holden, who now knows only too well just how nerve-wracking an experience that is by taking to the stage and belting out a hit from Frozen during the recent round of auditions – with less than successful results…

The BGT judge gave an impromptu performance during auditions at Birmingham’s Hippodrome Theatre last week.

Wearing a distinctive black and white striped outfit, the 44-year-old star sang along to the Disney mega-hit Let It Go as fellow judges Alesha Dixon and David Walliams watched on.

However, she didn’t even get to the chorus before the audience started to playfully chant: ‘Off! Off! Off!’

And in video footage shared by one audience member on Twitter, Amanda then seemed to comically throw down her microphone as the heckling got louder, whilst Ant & Dec watched on giggling in the background.

Amanda’s attempts at singing the now-iconic song apparently came as Ant joked that this would be her last year on the ITV talent show – after which, Amanda walked out on stage to the sound of the Spice Girls’ hit Goodbye.

But later she ran on stage telling the crowd that it was ‘utter b**s’, adding: ‘I’m not leaving. I was thinking that I’m going to have a fantastic song to walk down to.

‘I asked for Time Warp or Frozen… And I got the bloody Spice Girls!’

She then demanded that producers play Let It Go, saying: I’m not leaving the stage until you do.’

Last week, Simon Cowell confirmed that Amanda and fellow judge Alesha would be returning for next year’s instalment of BGT, posting on Twitter: ‘Love my girls @AleshaOfficial @AmandaHolden so much that I just confirmed them both for next year.’
