Simon Cowell was pictured having a heated discussion in the street with his partner Lauren Silverman.

The heated discussion occurred as the music mogul, 61, headed out for a dog walk with Lauren, 43, and their son Eric, seven, in London on Friday, February 26.

In the pictures, Simon and Lauren appeared deep in a heated discussion. At one point, Lauren was seen walking away from Simon who then tries to stop her.

According to onlookers, the pair appeared to be ‘very fraught’ and walked at a distance to each other following the conversation.

A passer-by told The Sun: ‘Simon started to walk off and Lauren was walking behind him. Then he stopped and they seemed to be rowing. Simon had a face like thunder.

‘It appeared to be very fraught. Lauren turned to move off and Simon put out his hand as if he didn’t want her to walk off.

‘Lauren put her hand up close to her mouth and made a gesture. Simon looked annoyed and got out his phone and started ringing someone.’

They added that both seemed ‘pretty annoyed’ and walked in the same direction but at a distance.

However, a source close to the family disputed the claims and said the couple were ‘happier than ever’.

The pal said: ‘Simon and Lauren weren’t having a tiff at all. They are happier than ever.

‘They have been together throughout lockdown and, with Eric, were just walking in the park – like so many families at the current time.’

A spokesperson for Simon also denied claims there was a heated discussion and told MailOnline: ‘There was no row or argument whatsoever.’

Simon has been with Lauren since 2013. She has another son Adam, from her marriage to Andrew Silverman.
