Simon Cowell’s ex Sinitta has claimed that the music mogul will never marry his partner Lauren Silverman.

Sinitta, 56, who is part of Simon’s close group of friends, has said that the entertainment mogul will never propose to Lauren, 42, who he shares son Eric, six, with.

It comes after Simon’s Britain’s Got Talent co-judge Amanda Holden’s daughter Hollie, eight, sparked confusion earlier this month after she said the couple had split during an Instagram Live.

While earlier this week, Simon and Lauren hit back at claims that she accused him of having an affair with Mel B.

In an interview with The Sun, Sinitta said: ‘You never know what is going on behind closed doors, so I won’t buy a hat for their wedding.’

Sinitta dated Simon 40 years ago and insists that Lauren needs to relax when it comes to her boyfriend’s friendships with female colleagues.

She said: ‘There was no Mel B affair. They are good friends and Lauren should not have been so worried and upset about it.

‘She has nothing to be upset about.’

A source close to the couple rubbished reports that Lauren furiously claimed Simon was having an affair with Mel, which they both denied, and has insisted they are ‘very happy’ and continuing to isolate together in Los Angeles.

The source exclusively told MailOnline: ‘Clearly this story is utterly ridiculous and completely pointless – because there was no affair.

‘Simon and Lauren are very happy together as a couple. They have been in lockdown together in LA for more than six weeks now.’

It came just hours after Simon’s Britain’s Got Talent co-judge Amanda Holden’s daughter Hollie also sparked confusion about whether the couple had split during an Instagram Live.

Amanda, 49, had been reminiscing about the moment she played her charity single to Simon, before going onto mention Lauren, who had sent her pictures of the family cooking.

Speaking to her 1.4 million 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.

Simon and New Yorker Lauren started dating in 2013 but the pair still haven’t commented on whether they plan to marry.
