If you're planning to perform for Simon Cowell any time soon, X Factor host Dermot O'Leary has some advice for you.
Having just filmed the latest round of auditions for The X Factor 2016, it seems that there are songs by one artist that Simon has just had enough of.
Dermot revealed this week: "A lot of people do Adele and you want to take them aside and go: 'What are you doing? Have you lost your mind?'
"Simon puts his head in his hands. It has sort of been a sport for me," he told the Daily Star newspaper.
It's not the first time that Adele's tracks have caused issues on one of Simon's shows.
It was reported earlier this year that during filming for Britain's Got Talent producers BANNED her songs after so many singers wanted to perform them.
"The producers were sick of hearing the same songs over and over again," a source revealed at the time. "They had to start telling people to sing material from another artist.”
So there you have it, what NOT to sing for Simon!
