If most men were married to Kim Kardashian their grin would probably be so wide they couldn't fit through the front door. But not Kanye West.

Legendary miserablist Kanye, 37, is less likely to crack a smile than his missus is to win a Nobel Peace Prize and he's finally revealed the two reasons why.

1. Not smiling makes him smile
2. When you see old paintings in a castle the people on them are not smiling

Right, well that clears that up then doesn't it.

Kanye demonstrates his "face like thunder" pose

Kanye made the mind-boggling statements at the Fashion Los Angeles Awards, saying: "Back when I was working on Yeezus, I saw this book from the 1800s and it was velvet-covered with brass and everything.

"I looked at all these people's photos, and they look so real and their outfits were incredible and they weren't smiling.

He has a point

"People, you know the paparazzi, always come up to me, 'Why you not smiling?' and I think, not smiling makes me smile. When you see paintings in an old castle, people are not smiling because it just wouldn't look as cool."

Kanye has been known to smile on extremely rare occasions and we don't think his cool points suffer at all for flashing the odd grin.
