Kanye and Kim Kardashian West are expecting their fourth child via surrogate, PEOPLE has confirmed.
The baby on the way will join big siblings Chicago, 1 this month, Saint, 3, and North, 5½.
Although Kardashian West has made it clear that she loves being a mother, in August, a Keeping Up with the Kardashians source told PEOPLE that the 38-year-old reality star and rapper West, 41, weren't "in a huge rush" to give their three children another sibling.
