Amanda Holden puts on a giddy display as she twirls around in rainbow dress

Her daughter recently sparked confusion by claiming Simon Cowell and Lauren Silverman had split up during an Instagram live.

But Amanda Holden, 49,  brushed off the drama as she was pictured leaving the Heart FM radio studios in London wearing a rainbow coloured mini dress.

The BGT  judge also shared an Instagram of herself wearing the ensemble as she walked and twirled her way down a corridor at the studios.

The video comes after Amanda’s daughter Hollie, eight, baffled viewers by claiming Simon and Lauren had gone their separate ways. 

Amanda was reminiscing about the moment she played her NHS charity single to Simon, 60, at his house, before mentioning Lauren, 42, who’d recently sent her pictures of the family cooking.

But Amanda’s daughter Hollie, eight, interrupted the recording by saying: ‘I thought they broke up?’ – with the singer quickly telling her ‘Don’t be stupid.’

Speaking to her 1.4million followers, Amanda said: ‘I did play the album to Simon because Simon was very kind and he invited me to come and sing on Britain’s Got Talent live shows, which I still will do whenever that is.

‘But I thought I’ll take it round and have a cup of tea and see what he thinks, I don’t know why I did that – it was one of the most nerve-wracking things I have ever done in my whole of my life. It was like the opening night of a West End show.

‘I was sat in his lounge; I had some lovely homemade biscuits from Geoff the chef. I don’t think they have a chef in lockdown. 

‘In fact, lovely Lauren, Simon’s girlfriend, sent me some lovely pictures of them cooking the other day. Simon’s quite good at cooking, I think.’

Hollie said: ‘I thought they broke up?’

Amanda replied: ‘Simon and Lauren?’ Before Hollie said: ‘Yeah.’

In a panic Amanda replied: ‘Don’t be stupid.’

During the broadcast, Amanda then appeared to nudge her daughter in an attempt to silence her from revealing any more details – with Hollie flinching and letting out a noise indicating she was in pain.

The live took place at Amanda’s home in her lounge and she wore matching floral silk pyjamas to Hollie.

A spokesman for Simon told MailOnline: ‘Simon and Lauren are very much still together and are in lockdown together in California.’ 

Simon has been isolating in the States along with longterm partner Lauren, their son Eric, six, and Adam, 14, who Lauren’s a mum to from a previous relationship. 

The family has been pictured together throughout lockdown – wearing protective masks and going on bike rides to keep fit.

X Factor boss Simon was last pictured on his own during a shopping trip on Sunday. 

Simon and New Yorker Lauren started dating in 2009 but the pair still haven’t commented on whether they plan to marry.

Heart presenter Amanda has been celebrating her charity single Somewhere Over The Rainbow topping the iTunes charts, with all proceeds going to the NHS. 

The TV star told MailOnline she was excited to tell Simon about her achievement, saying: ‘Simon doesn’t know yet. 

‘As soon as LA wakes up I’m going to be straight on the phone to Lauren because Simon doesn’t use a mobile phone.’ 

A spokesperson for Amanda declined to comment.
