Kim Kardashian West is suffering from ''really bad'' morning sickness.

The 'Keeping Up With The Kardashians' star - who confirmed she was expecting her second child with her husband, rapper Kanye West, yesterday (01.6.15) - has confessed she has struggled with nausea since falling pregnant and has even found it difficult just to get out of bed.

The raven-haired beauty - who already has a 23-month-old daughter North with Kanye - said: ''To be honest, I've had really bad morning sickness, day sickness, night sickness - I can barley get out of bed.''

The 34-year-old reality TV star - who has been documenting her difficulties conceiving for the second time on the E! reality series - insisted feeling ''s**t* is ''so worth it'' as the couple had worried they may never be able to add to their brood.

She told Us Weekly: ''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.''

It was first revealed Kim was expecting once again during a teaser at the end of the midseason finale of 'Keeping Up With The Kardashians' on sunday night (31.05.15).

The thrilled star expresses her relief at having finally fallen pregnant for the second time as she chats to sister Khloe Kardashian, 30, in the clip from an upcoming episode.

She says: ''I just got the blood test back, and I am pregnant!''

And Kanye, 37, is said to be equally excited about their new addition.

Kim's trainer, Gunnar Peterson said ''A lot of people worry that being a dad will take away from work or couplehood, but Kanye has gotten better at everything since he's become a dad.''
