Kim Kardashian West and Kanye West have confirmed reports that they’re expecting their fourth child—a son, via surrogate. Kardashian West made the announcement on Watch What Happens Live with host Andy Cohen, and said she let the news slip when she’d had a bit too much to drink at a festive gathering. “Are you working on another child?” Cohen asked. “We are,” she responded. “It’s a boy, I think it’s been out there... I got drunk at our Christmas Eve party and told some people. I can’t remember who I told because I never get drunk.” Rumors of the pregnancy have been swirling for weeks, but Kardashian and husband Kanye had declined to comment until now. The baby is expected in May and will join siblings North West, 5, Saint West, 3, and Chicago West, 11 months.
