In a video posted on Twitter on Thursday, Dec. 1, the 63-year-old TV host tells people who want to try out for "Britain's Got Talent" to get in touch with him.
Simon Cowell has gotten a lot of attention online because he looked like a different person in a Twitter video just a few months after saying he was done with Botox.
But his new look made people laugh more, and a lot of people shared the video and made fun of him.
People said he looked like a "Madame Tussauds waxwork."
Others said that his new look shows that he has had some kind of cosmetic surgery.
A few people who keep an eye on social media seemed worried that something more serious might be wrong.
One fan wrote on Twitter, "Simon Cowell doesn't look good. There's something wrong."
