As if Khloe Kardashian wasn't already an open book since she confirmed her pregnancy, the first time mom has continued to share details with her fans.

On Tuesday, March 6 the Keeping Up With the Kardashians star took to her app to share the story behind her pregnancy announcement photo.

"One day when [Tristan] came home from practice, we just decided to do it!" Khloe explained.

When asked why her and Thompson's face were cropped out of the photo, Khloe joked that they both looked crazy at the time. 

Khloe Confirms Her Pregnancy

As previously reported, Kardashian waited three months before confirming that she and her boyfriend, Tristan Thompson, were expecting.

In an interview with Lorraine, Khloe explained that she decided to follow doctor's orders before disclosing the news.

"Honestly, at first it's not safe to say anything and the doctor was like, 'I would just want to wait, for you.' So I was listening to doctor's orders," Khloe said. 

However in December 2017, the Revenge Body star took to her Instagram to share the exciting news with her followers.

"My greatest dream realized! We are having a baby! I have been waiting and wondering but God had a plan all along. He knew what He was doing. I simply had to trust in him and be patient," the 33-year-old captioned the photo.

It's A Girl

After months of teasing her fans about the gender of her child, Kardashian finally revealed that she and Thompson will welcome a baby girl on the season finale of Keeping Up With the Kardashians. 

In the episode, Khloe's little sister, Kylie Jenner, was the one to reveal the news to her, while she was in San Francisco with older sisters Kim and Kourtney Kardashian. 

Khloe will reportedly give birth sometime in April.
