SIMON Cowell fans have all been left saying the same thing after he was spotted looking very different on The One Show.
The television personality sat down with Alex Jones and Ronan Keating to promote a new record written by Lucy Spraggan.
Simon, 63, sat down on the sofa beside Lucy, 31, who rose to fame on The X Factor in 2012, to talk about her single Process.
The Britain's Got Talent judge smiled wide as he told the hosts he wanted to promote the emotional record, ten years after the singer-songwriter made it to the X Factor final.
However, fans were left distracted by Simon's appearance, as they flooded Twitter to discuss how "different" he looked.
Simon has lost four stone in recent years after a lifestyle overhaul that saw him embark on a health and fitness regime.
It's left him looking very different - with a noticeably slimmed down face - and fans couldn't help but notice it.
"Simon Cowell looks nothing like his original self," one said, as another added: "Simon who? Don't recognise him."
A third wrote: "Is this the same person? Simon Cowell?" as a fourth said: "Can't believe this is Simon Cowell..."
A fifth concluded: "I can't stop looking at Simon Cowell..."
Last week, Simon was seen looking equally unrecognisable after his impressive weight loss as he appeared in a new video.
Simon appeared to have put his ageing in reverse in a new video, where he fronted a clip with dazzling white teeth.
The reality TV judge has lost four stone in recent years after a lifestyle overhaul that saw him embark on a health and fitness regime.
The star has admitted he used to binge on sausage rolls, burgers and jam tarts made by his personal chefs.
However, since ditching his unhealthy lifestyle after suffering a fall at his London home in 2017 he has dropped four waist sizes.
Appearing in the video he urged viewers to get in touch with their audition efforts ahead of BGT's return.
He said: "I always say on this show, two or three minutes can change your life. And it has. And maybe this time it's gonna be you.
"So please audition now for next year's season and I look forward to meeting you."
Several fans remarked on the TV star's new look, with one tweeting: "Simon Cowell gets younger and younger each year."
