ET Canada has reached out to Kardashian and West’s rep for comment, but they did not immediately respond.
Kardashian and West used a surrogate for their third baby, 11-month-old Chicago, after Kardashian suffered high-risk complications during her previous pregnancies with North, 5, and Saint, 3.
Last year it was reported that the couple had one embryo left, and now new reports say the upcoming Kardashian is due in May.
