By now, everyone probably knows that Khloe Kardashian and Tristan Thompson will welcome a baby girl. Though it may be exciting, it took a minute for the news to really to sink in with the first time mom.

On Sunday's finale of Keeping Up With the Kardashians, the Good American learned that she was expecting a girl while on the phone with her little sister, Kylie Jenner, who was actually the one to reveal the gender to her.

"You're having a girl," Jenner could be heard saying over the phone.

Shortly after learning the news, the 33-year-old stated that she thought Kylie was lying and she didn't feel like she's having a girl. Khloe further revealed that she actually thought she would be welcoming a baby boy.

"I just was convinced that I'm having a boy, so to be having a girl it's like, Okay that wasn't what I thought was going on," the Good American designer said.

Khloe then called her mother, Kris Jenner, who was able to relate to her as she only ended up with one boy and three girls.

Khloe's Baby Girl

Now that Khloe had the time to process the news, she took to Twitter and expressed her excitement to be giving birth to a baby girl.

When a fan asked the mother-to-be if she was going to follow along with tradition and name her daughter with a K name, Khloe stated that a T name was also an option as she's currently still undecided.

The reality star further revealed that she already had a name picked out for a baby boy.

One Month Until Khloe Gives Birth

After rumors spiraled that Khloe and Thompson were expecting back in September 2017, Khloe finally confirmed the news via Instagram in December 2017. The Revenge Body star shared a photo of her growing belly. 

"I am so thankful, excited, nervous, eager, overjoyed all in one! But it's the best bundle of feelings I've ever felt in my life!" Khloe wrote.

Khloe will reportedly give birth sometime in April.
