So that's why Kim Kardashian always seems so grim in photos!
The reality TV star is famous for refusing to crack a smile on the red carpet, but now we finally know why. (Hint: it's totally on purpose.)
Kim captioned the pic, "See I do smile... even laugh on occasion. Not too often though because it causes wrinkles @shammaurice."
While we can't prove the validity of Kim's claim, we do know that the Vogue cover girl looks even more gorgeous when she has a big smile on her face.
The 34-year-old mom isn't the only celebrity who's famous for favouring a pout. Victoria Beckham is notorious for maintaining a scowl whenever she's photographed, whether it be on or off the red carpet. "I actually used to smile a lot in pictures," the former Spice Girl told Glamour magazine in 2012. "I think I only stopped smiling when I got into fashion. Fashion stole my smile! I've created this person. And I'm not saying that's not me, but I wouldn't say that's the whole me … It's an armour that goes up."
Although we would like to see these gorgeous gals smile a bit more, we wouldn't change them for anything.
