The Keeping Up with the Kardashians star, who is currently expecting her second child with long-time partner Scott Disick, confessed that she became extremely claustrophobic while stopped in a tunnel after returning from a recent trip to Mexico, a feeling she attributes to the third trimester of her pregnancy.
"I had a small panic attack in customs when they stopped everyone in a tunnel," Kardashian recalled on her blog.
"Looking behind me all I could see was people and in front of me tons of people and I couldn't even tell where the tunnel ended. I had to just run to the front of the line because I literally couldn't breathe."
Kardashian added: "It's a horrible feeling and I'm hoping that it goes away after my pregnancy. I hate that feeling of being trapped with no control. Ahhh deep breath!"
The 33-year-old recently revealed that her 3-year-old son Mason is excited to become a big brother, although Disick is nervous about having a girl.
