"I'm just eating whatever I can. Whatever I can tolerate," she said. "I think this [pregnancy] there is less I can tolerate."
Kardashian, 32 – who already has a son, 2-year-old Mason – recently announced she's pregnant with her second child, but said it's too early to tell whether Mason will have a little brother or sister.
Joined earlier this month by her family and longtime boyfriend Scott Disick at Las Vegas's Kardashian Khaos, a lifestyle boutique in the Mirage Resort and Casino, the Kourtney and Kim Take New York star's baby bump was barely noticeable in her black dress.
Though she doesn't know the sex, she hinted that she won't be surprised when the child is born. Asked whether she wants to know in advance, she said, "I think so."
