Reality TV star Kim Kardashian and rapper Kanye West are expecting their fourth child — a boy — via surrogate.

Multiple sources have confirmed in the new issue of Us Weekly magazine.

In August, the magazine reported that the couple, who used a surrogate for their third child, 11-month-old Chicago, had one embryo left, a male.

Now he is due to arrive “in very early May”, said a source.

In addition to Chicago, the couple are also parents to North, 5, and Saint, 3.

Another source said Kim, 38, “always wanted four kids”.

The Keeping Up with the Kardashians star was advised by doctors not to get pregnant again after suffering complications when expecting daughter North, four, and son Saint, two, so she and husband Kanye West used a surrogate to carry their daughter Chicago.
