Kim Kardashian and Kanye West are expecting their fourth child via surrogate

Kim Kardashian and Kanye West are expecting their fourth child together.

The celebrity couple are expecting another baby, their second via surrogate, a source confirmed to E! News.

This happy news comes less than a year after the pair welcomed their third child, 11-month old daughter Chicago, who was also born via surrogate.

Kim and Kanye are also parents to five-year-old North and three-year-old Saint, who the model and reality TV star birthed without the aid of a surrogate mother.

A source told E! News that: ‘the surrogate is well into the pregnancy’.

‘She is due in May and everything looks good,’ adding: ‘Kim and Kanye have known for a while and are very excited.

‘They had one male embryo left and are thrilled it has worked out.’

The Keeping Up With The Kardashians star, who last year confirmed that she used gender selection for her third baby Chicago, has previously been open about her difficult pregnancies and health complications when it has come to carrying her children.

During her past pregnancies the mum-of-three, who has spoken about how she ‘almost bled to death giving birth’, suffered from pre-eclampsia, which causes dangerous high blood pressure and placenta accrete, a condition which leads placenta to become too deeply attached into the womb.

‘After giving birth, your placenta is supposed to come out. But mine was stuck’, Kim told ELLE magazine last year.

‘That’s what women usually die from in childbirth – you haemorrhage and bleed to death and they can’t stop it.’

‘To get it out – it’s so disgusting – the doctor had to stick his whole arm in me and scrape it off. It was the most painful’, she continued.

The 38-year-old also revealed to the magazine that she would likely not have any more than four children.

‘I don’t think I could handle more than that’, she told the publication. ‘My time is spread really thin. And I think it’s important that in all couples, the mum give the husband as much attention as the kids.’
