Khloe Kardashian is expecting a baby girl. 

The 'Keeping Up With the Kardashians' star has revealed she's having a daughter with her partner Tristan Thompson and is thrilled her little one will grow up with her sisters Kylie Jenner's four-week-old daughter Stormi and Kim Kardashian West's two-month-old daughter Chicago, who was born via a surrogate earlier this year. 

Taking to her Twitter account on Sunday, March 4,  the 33-year-old beauty wrote: "God gives us what we need! His timing is never wrong! my hormones were IN RARE FORM for that news. I am now so excited my daughter will have forever best friends with Chicago and Stormi!! God is great!!! Thank you Lord for our princess. (sic)"


The news was also announced on Sunday night's episode of 'Keeping Up With the Kardashians' when Khloe's doctor told Kylie the sex of the baby and then the 20-year-old businesswoman relayed what she had been told via a gender reveal cake. 

But Khloe didn't seem overly impressed and admitted she was hoping her younger sibling was "lying" because she was convinced she was expecting a little boy. 

She said: "I'm really hoping Kylie's lying."

Earlier on in the episode, Khloe was riddled with anxiety ahead of the big reveal.

She explained: "I have such anxiety and nerves to find out what I'm having."

The reality TV star sent the world into a frenzy earlier this year when she confirmed that she and Tristan, 26 - who have been dating since 2016 - were expecting a baby.

Alongside a photograph of her baby bump, she wrote: "My greatest dream realized! We are having a baby! I had 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. I still at times can't believe that our love created life!

"Tristan, thank you for loving me the way that you do! Thank you for treating me like a Queen! Thank you for making me feel beautiful at all stages!

"Tristan, most of all, Thank you for making me a MOMMY!!! You have made this experience even more magical than I could have envisioned!

"I will never forget how wonderful you've been to me during this time! Thank you for making me so happy my love!

"Thank you to everyone for the love and positive vibes! I know we've been keeping this quiet but we wanted to enjoy this between our family and close friends as long as we could privately. 

"To enjoy our first precious moments just us Thank you all for understanding. I am so thankful, excited, nervous, eager, overjoyed and scared all in one!
"But it's the best bundle of feelings I've ever felt in my life! (sic)"
