Kim Kardashian Confirms She and Kanye West Are Expecting a Baby Boy

The expectant mom confirmed the news on Monday's 'Watch What Happens Live'

Kim Kardashian West and Kanye West are adding another son to their growing family.

The Keeping Up With the Kardashians star and her famous sisters sat down with Andy Cohen on Monday's Watch What Happens Live, and Kim confirmed that she is expecting another baby boy.

"Do you know if it's a boy or girl?" Cohen asked.

"We do. It's a boy, I think," said Kim, who revealed earlier this month that she and her husband were expecting their fourth child together, once again via surrogate.

"What?" Kourtney Kardashian exclaimed at Kim's admission. "Obviously I knew that, but I didn't know you were telling everybody."

Kim went on to explain that she's OK with confirming because, she said, "I got drunk at our Christmas Eve party and I told some people, and I can't remember who I told, because I never get drunk."

The expectant couple's forthcoming little boy will give the pair an even number of sons and daughters. Kim and Kanye are already the proud parents of 5-year-old daughter North, 3-year-old son Saint, and their youngest daughter, Chicago, will celebrate her first birthday on Tuesday.

"The couple has always wanted a big family, and their first time with surrogacy went so well, they decided to do it again," a source told ET on Jan. 2. "The couple is excited to welcome such an incredible gift in 2019. They’ve also talked that after this child, they are most likely done having kids."
