Simon Cowell displays slimmer physique during stroll with girlfriend Lauren Silverman and son Eric

He has proudly been flaunting his 20lbs weight loss and even spectacularly donned a bright red top on America’s Got Talent in a bid to continue his image overhaul. 

And Simon Cowell, 59, looked in high spirits as he enjoyed a low-key stroll with his girlfriend Lauren Silverman and their five-year-old son Eric in Pacific Palisades, California on Monday. 

The talent show judge showed off his newly slimline physique in a light powder blue top and white shorts as he soaked up the sunshine with his family.

Simon kept the sunny rays at bay with a pair of shades as he strolled along with Lauren, who looked casually chic in a black top and midi-skirt. 

The couple looked happy as they sauntered along in the sunshine with sweet little Eric.  

This comes after Simon continued with his image overhaul as he forewent his signature white top and casual blue jeans for a bright red top to judge the quarter finals on America’s Got Talent on Tuesday night.

The British music mogul’s rare splash of colour left viewers completely divided as some confessed his outfit made them feel ‘uncomfortable’ while others gushed that ‘red was his colour.’

Simon, who has also served on the judging panel of talent shows such as American Idol, Britain’s Got Talent and The Factor since 2001, has most famously been known for his fuss-free casual ensembles. 

His go-to looks usually consist of a pair of casual blue jeans, which he interchanges with a slew of white, grey and faded black tops. 

However, on Tuesday night, AGT viewers were thrown for a loop when Simon took to the judging panel in a red top. 

While the cut and style of the top was similar to his usual favourites, the bold colour left a few fans unconvinced as they tweeted: ‘Simon Cowell’s red shirt on #agt tonight has thrown me.’

He told Best Magazine: ‘People have said: “Oh, he’s had a gastric band fitted”- but I haven’t. If I had, I would admit to it. This diet is all about what you put into your body.

The judge has overhauled his lifestyle after a health scare in 2017, giving up sugar, fatty foods and unhealthy drinks.

‘I met this doctor in LA and he told me my diet was appalling and I had to cut out fatty foods and certain drinks.
