Kim Kardashian West has confirmed that she and her husband Kanye West are set to welcome a fourth child to their family.

At the start of the month, it was reported that the couple were expecting a baby boy by surrogate.

Reality TV star and entrepreneur Kardashian appeared on Watch What Happens Live with Andy Cohen where she confirmed that the reports were true.

While appearing alongside her sisters Kourtney and Khloe, Kim said the baby was due "sometime soon", and said: "It's a boy."

Kourtney seemed shocked when Kim confirmed the baby's gender, saying "What? I mean obviously I knew that, I couldn't believe you were telling everybody!"

Kim continued: "Well, it's out there. I got drunk at our Christmas Eve party and I told some people. I can't remember who I told, because I never get drunk."

The couple are already parents to five-year-old daughter North and three-year-old son Saint.

They welcomed daughter Chicago via surrogate last January. 

Kardashian and West used a surrogate for their third baby after Kardashian suffered high-risk complications during her previous pregnancies.
