Simon Cowell continues to raise eyebrows with his “unrecognizable” appearance after taking to the stage in London for the “Royal Variety Performance.”

The UK special was filmed on Dec. 2 and aired on Tuesday night. The 63-year-old music mogul left some viewers distracted by his new visage, with many speculating he’s undergone plastic surgery.

“Just saw Simon Cowell on the Royal Variety Show. What has he done to himself?” one Twitter user commented.

“It’s Simon Cowell look alike – Simon Cowell…” another wrote.

Earlier this month, Cowell left fans concerned after appearing in a now-deleted video posted on his social media accounts to promote “Britain’s Got Talent.” Cowell was encouraging contestants to audition for the show, but instead, Twitter users commented on his seemingly enhanced features and suggested it was some kind of cosmetic procedure.

Others were quick to urge the former “American Idol” judge to quit receiving botox injections, which he previously vowed to do after receiving a facelift in 2018. The “America’s Got Talent” judge also removed his face fillers earlier this year.

“There was a phase where everyone was having their faces pumped full of this and the other,” Cowell said at the time. “There was a stage where I might have gone a bit too far. I saw a picture of me ‘before’ the other day, and didn’t recognize it as me first of all. Enough is enough. There is no filler in my face at all now. Zero.”

While it’s not clear whether he had work done, Cowell famously lost 20 pounds over the past two years. He also overhauled his lifestyle after he broke his back when he crashed his electric bike near his Malibu home in 2020.

During an interview with “Access Hollywood,” Cowell downplayed the injuries and mostly complained the accident was “annoying” because he could not ride his bike.
