Her husband Kanye West may be infamous for refusing to smile for the press, but now Kim Kardashian has shared her own reason for staying stoic in front of the camera. (And no, it’s not just to copy Kanye.)

In a new interview with C Magazine, the 34-year-old star admitted that she’s stopped smiling in photos because of the way her looks were scrutinized during her first pregnancy. She suffered preeclampsia, or pregnancy-related high blood pressure, when pregnant with her daughter North West. The condition caused bloating, which in turn caused tabloids and fans alike to mock her appearance.

"I couldn't help it, and everyone would say, 'She can't stop eating,'" Kardashian said. "I delivered at 180, and they were like, 'She's 210 pounds. She's getting dumped because she's too fat,' and all these ridiculous stories. It really took a toll."

In response to all the body-shaming, Kardashian, who’s now pregnant with her second child, simply stopped smiling for the camera. "I just didn't feel like being that girl who was going to be smiling for every photo,” she admitted. "It changed my mood; it changed who I was; it changed my personality a lot."

Having a happy family doesn’t always mean you’ll want to look happy for the press -- especially when you’re under as much pressure as Kim. Hopefully she still has plenty to smile about even if she won’t do it for the camera.
