Simon Cowell
Simon Cowell committed the ultimate tanning faux pas back in 2016 — putting his spray tan ahead of his commitments. We understand that preparing for the day can be time-consuming, especially when you know you'll be on TV.
However, proper planning can ensure that people appreciate your appearance rather than become annoyed. Unfortunately, Simon didn't see it that way. He kept his Britain's Got Talent fans waiting for a whole hour while he indulged in a tanning booth.
