We know why Kim Kardashian looks stone faced in photos, but her husband Kanye West is now explaining why he prefers not to smile when getting his picture taken.

Kardashian has said she doesn’t smile in photos because she doesn’t want to get wrinkles. She captioned a photo of herself smiling, “See I do smile... even laugh on occasion. Not too often though because it causes wrinkles.”

During a speech at The Daily Front Row's first-ever Fashion Los Angeles Awards, the Yeezus rapper said he doesn’t smile because it doesn’t look “cool," E! Online reports.

He explained he was inspired by this book “from the 1800s and it was velvet-covered with brass and everything.”

West explained, “I looked at all these people's photos and they look so real and their outfits were incredible and they weren't smiling and 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 cause it just wouldn't look as cool.”
