Plenty Of Famous Non-Actors Have Tried Their Hand At Acting, But Whose Onscreen Debut Was The Worst?

There are plenty of triple and quadruple threats in Hollywood, but not every performer is destined to be a jack of all trades. Sometimes, a non-actor decides to branch out and take on a new role — but it's not always well-received.

For example, Ed Sheeran's Game of Thrones cameo was so ill-received by online commenters that he ended up deleting his Twitter account.

And even Kelly Clarkson herself knew that From Justin to Kelly was "going to be real, real bad."

And Mariah Carey's first big role in Glitter earned her the Worst Actress Award at the Razzies.
