Rumours about another baby on the way swirled in early January, though the Keeping Up With the Kardashians star didn't confirm the news until the middle of the month while appearing on Watch What Happens Live With Andy Cohen.
"Are you working on another child?" Cohen asked.
"We are," she responded.
"It's a boy, I think it's been out there," she added. "I got drunk at our Christmas Eve party and told some people. I can't remember who I told because I never get drunk.
A woman named La'Reina Haynes carried Chicago for Kim and Kanye, but the couple used a different surrogate this time around because Haynes was pregnant with a child of her own, as The New York Post previously reported. Kardashian gave birth to her two older children.
Kardashian previously revealed that her sisters Khloe and Kourtney and her good friend Chrissy Teigen had offered to be her surrogate in the past following her health concerns.
Although one-year-old Chicago was too young to understand that a new baby was coming, the E! reality star said in January that five-year-old North and three-year-old Saint were looking forward to the addition.
"They are excited," Kardashian said. "I mean, I don't know if they don't feel it as much because they don't see my big belly and probably hear me complaining every two seconds. But, we do talk about it a lot, so I think they are really excited. I think my son, I don't know how he is going to react because he doesn't get it yet, but my daughter is really excited."
