SIMON Cowell and his partner Lauren Silverman appear to have a heated row in the street before she walks off.
Onlookers said the X Factor mogul, 61, had a “face like thunder” during the exchange.
He and Lauren, 43, were walking a dog with son Eric, seven, when an argument appeared to start.
One passer-by said: “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.
"He crossed over on to the other side of the road and Lauren carried on walking without him.”
The onlooker added of the incident in London last Friday: “It was odd as they walked in the same direction but not together.
"Both of them seemed pretty annoyed.”
The couple have been together for almost eight years and started dating while she was still married to Andrew Silverman, 46.
She has a son Adam from her marriage to Andrew.
A source close to the family said: “Simon and Lauren weren’t having a tiff at all.
