Nope, she isn't grabbing for the ice cream and pickles. Instead, Kourtney Kardashian is opting for healthier choices now that she's eating for two
"I have more healthy cravings than my normal eating habits, like I crave fruit and cold things like smoothies," she said at the launch of her new show, Kourtney and Khloe Take Miami
, at MGM Grand's Wet Republic pool party in Las Vegas.
While celebrating at the pool party, Kardashian, who steered clear of alcohol, noshed on fruit platters in her private cabana.
"I wasn't normally a breakfast person. [Now] I eat breakfast the second I get up and I'm definitely hungry all throughout the day," she said last weekend, hiding her baby bump with a loose blouse and jean shorts.
But it's going to get harder to keep her baby weight out of sight: The reality star, who is due around Christmas, admits she's already gained more than 10 pounds.
"I like when you can see it," Kardashian says of her bump. "I, like, run around naked all day at home."
Also enjoying her new curves is the baby's daddy
, Scott Disick.
"He's always been obsessed with Kourtney, but he's definitely becoming more ... paternal," says Kardashian's sister, Khloe.
