Kim Kardashian West has confirmed that she and husband Kanye West are expecting their fourth child via surrogate.

On Monday night’s episode of Watch What Happens Live with Andy Cohen, Kardashian West, 38, revealed the news after Cohen, who also recently announced he’s expecting his first child via surrogate, asked if she was “working on another child.” “We are,” Kardashian West responded. The Keeping Up with the Kardashian star also revealed the baby is due “sometime soon.”

“It’s a boy, I think it’s been out there,” Kardashian West told Cohen. “I got drunk at our Christmas Eve party and told some people. I can’t remember who I told because I never get drunk,” Kardashian West added. Multiple sources previously confirmed to PEOPLE that the couple’s fourth child is a son. Kardashian West and West, 41, are already parents to daughter North, 5, son Saint, 3, and daughter Chicago, 11 months. While the reality star and rapper used a surrogate for Chicago, a source said that the gestational carrier for their baby boy on the way is a different woman. “Since they had another embryo, Kim and Kanye always knew they wanted to try and implant that embryo too,” the insider said. “They hoped to work with the same gestational carrier, but it didn’t work out this time. They are working with a second carrier now that is pregnant and will give birth in the spring.”
