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".
