While pregnant with her now 5-month-old baby Penelope, Kourtney Kardashian admitted that she, too, was a victim of morning sickness.
“The beginning was different because I had a lot more morning sickness than last time,” she said of her second pregnancy. “I was also more tired but that's probably because I'm chasing after a toddler most of the time.”
But Kourtney is just the tip of the iceberg. Tons of other celebrities have battled— and are just beginning to battle— nausea from morning sickness. In fact, the same day that the expecting dutchess was admitted to King Edward VII Hospital in Central London, pregnant Playboy model Holly Madison was also hospitalized in LA for the same ailments.

Keeping me entertained -- forgot to bring a book with me," she continued.
And the list just goes on and on!
