The 34-year-old socialite is expecting her second child with husband Kanye West, reported Ace Showbiz.
"To be honest, I've had really bad morning sickness, day sickness, night sickness - I can barley get out of bed," said the mother of one.
"It's a very different type of pregnancy from my first one, but I'm so grateful to be pregnant when we didn't even think it was going to happen for us (so) I don't care how sick I am," she added.
