Kardashian took to social media the night before to make it clear just how ready she was to give birth.

Kardashian broke the news that she was pregnant in late May during a preview for the next season of her show Keeping Up With The Kardashians. She and West are already the parents of a two-year-old daughter named North.

The couple, who were married in May 2014, has struggled to overcome fertility problems — a battle that Kardashian openly discussed on the reality show.

In April, Time magazine named Kardashian, 35, and West, 38, to its list of the world’s 100 most influential people.
