She's best known for her daring outfits on Britain's Got Talent, so Amanda Holden certainly needs little encouragement when it comes to being 'naughty' during filming.

But the TV presenter has revealed that her boss, Simon Cowell, actively encouraged her, Alesha Dixon and David Walliams to play up to their naughty reputation whilst filming for Britain’s Got Talent: The Champions.

‘We always are naughty as a panel but Simon did pull us all aside before we went out on the first night and just said, “This is going to be great, have fun and be really naughty!’ I love that the boss tells us to be naughty, as if we need telling!”

Having done the show for 12 years, 48-year-old Amanda is just herself. ‘He’s always encouraged us to be our true selves and I am always obliging whether he really wants it or not!’

Speaking to The Daily Mirror, Amanda admitted Britain’s Got Talent – which has returned for a special series to celebrate the show’s alumni – helped change the public’s perception of her following her divorce from Les Dennis.

Having received a wave of backlash after her affair with Neil Morissey, Amanda – who is now married to Chris Hughes – felt ‘liberated’ when she joined BGT in 2007.

‘Starting out on Britain’s Got Talent was liberating for me,’ she said. ‘I mean, without dragging up my past, I think, at the time I was with Chris, we’d been together for something like five years but people still kept going on about Les and Neil, and all the other stuff.

‘So what was really nice was that anyone that might’ve had a preconceived idea of me could see who I really was and then really make their mind up.’

She also insisted she’s proud of being ‘naughty’ – but in a good way, unlike how she was portrayed in the press.

‘I was able to make a wider audience understand that I probably wasn’t as bad as I’d been portrayed, or as naughty,’ she added. ‘I am naughty, I stand by that, but in a good way! I think it’s important that everyone has a sense of humour in these difficult times.’
