If you're a famous person, you probably know that public relations is part of the job. Good PR is everything, because it can be tough competing with countless other people trying to promote their comedy or music albums or recently-leaked sex tapes. So you'd think most celebrities would think things through, before launching their latest attention-grabs. You'd be thinking wrong, because famous people screw this stuff up all the time.
And if there's a Facepalm Hall of Fame, you can bet all of these celebs are in it.
