Kim Kardashian is suffering from severe morning sickness after falling pregnant with her second child by rapper Kanye West.

The reality TV star revealed her baby news on Sunday night (31May15) during a preview for new episodes of her show Keeping Up With The Kardashians.

She has since told how the pregnancy has left her feeling nauseous all day and night, telling Us Weekly, "To be honest, I've had really bad morning sickness, day sickness, night sickness - I can barley get out of bed.

"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, I don't care how sick I am."

Kardashian and West have a daughter, North, who turns two later this month (Jun15).
