Game of Thrones star Kit Harington unveils new haircut ... and fans are NOT happy!

If you're still struggling to accept that Game of Thrones is coming to an end, we have some news that will really kick your mourning up a notch ...

Kit Harington (AKA Jon Snow) has finally cut his long and luxuriously curly locks.

Yep, it's over. It's really over.

Kit attended a photocall in London for the How to Train Your Dragon: The Hidden World film this week and fans were left distraught when they realised his long hair and scruffy beard had been traded in for a shorter 'do and a moustache.

Left doing a double take, followers compared the former medieval babe to looking more like a B-grade '80s porn star.

The actor actually cut his hair back in November, when filming finished for the final GOT season.

Of course, the change was inevitable, as Harington was only contractually obliged to preserve his curly locks for the duration of the HBO series ... not for the rest of his life.
