Hollywood isn't only famed for its style and elegance, but also for its fashion disasters, and the grooming sector isn't an exception by any means. Here, we take a look at one of the most favoured grooming trends of 2015 - the beard. Here are the five worst celebrity beards of 2015.

Justin Timberlake
Well, it's pretty evident that some faces were meant to sport a beard and others were not. There's something a little odd about a baby-faced man wearing a beard, and in Justin Timberlake's case, this rule firmly applies. Clean that up, Justin, seriously. 

Keanu Reeves
The 90s sex symbol decided to go all shabby on us with his recent facial hair growth, but if truth be told, it's not the fullest beard you'll ever see. This patchy mess just doesn't look right, and if Keanu wants to get back to the stylish man he once was, we'd advise him to shave this mess off!

Leonardo Dicaprio
What on earth happened to Leo? Ok, so we get it, the beard and bun is so totally in right now, but that's only if you can pull it off. Leo, we love your acting skills, seriously, we do, but that mess of a beard just has to go - or at least give it a good trim.

Brad Pitt
Ok, so we all know Brad Pitt can pretty much pull off any style he wants, because he's, well, Brad Pitt, but what's with all the facial hair in recent years? For a man blessed with the finest jawline in Hollywood, why the heck would he want that scruffy facial fuzz covering it up?

James Franco
No, just no. If you can't grow a full beard, then just don't bother at all. James Franco demonstrates the opposite to how a good beard should look. If you have a patchy face then seriously, just keep it clean until your genetics allow you to have a full beard.
