Kourtney Kardashian is suffering from morning sickness.

The 32-year-old star - who already has 23-month-old son Mason with her finace Scott Disick - is finding herself feeling queasy at all times as she prepares to enter the second trimester of her pregnancy.

Kourtney's sister Khloe told E! News: "She is having morning sickness. But it's not even in the morning. It happens any time, apparently."

Despite expecting their second child together, the reality TV star - who is 10 weeks pregnant - recently admitted she and Scott have no plans to marry in the near future, even though her mother Kris Jenner wants the couple to make their relationship more official.

Kourtney said: "I definitely don't want to get married just for the sake of getting married. This is my life. I don't need a piece of paper to make it a family unit. I don't want to get married right now and I don't have to listen to my mom or anyone else!"
