Khloe Kardashian To Reveal Sex Of Baby On KUWTK Season Finale

The reality star is about to drop some major baby news.

In a recently released promo for the upcoming season finale of Keeping Up With the Kardashians, Khloé Kardashian is seen revealing the sex of her baby to sisters Kim and Kourtney.

"Do you want to know what I'm having?" she asked as the three hung out in a hotel room on the family's trip to San Francisco. While fans will have to wait to watch the episode to find out the answer, the sneak peek clip cut to Kourtney's reaction. "I'm shocked!" she said while smiling, before she and Kim engulfed the expecting mom in a sweet group hug.

As Nicki Swift previously reported, multiple People sources claimed in fall 2017 that Kardashian, 33, and her NBA star boyfriend, Tristan Thompson, 26, are reportedly expecting a baby boy. However, the couple never confirmed this rumor.

Following months of speculation, the Revenge Body star finally announced that she and Thompson, who have been dating since October 2016, were expecting their first child together in December 2017. Thompson already shares 1-year-old son Prince with his ex-girlfriend, Jordan Craig.

"My greatest dream realized! We are having a baby!" Kardashian excitedly wrote on Instagram, captioning a black-and-white photo of her and Thompson's hands on her baby bump. "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!"

She added, "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!"

The cute pair reportedly plan on splitting their time between Los Angeles and Cleveland, Ohio — where Thompson plays for the Cavaliers — once their little bundle of joy arrives. And it sounds like the soon-to-be mom can't wait. "Khloé isn't worried about being a mother, she is more than prepared. Khloé has had training over the years with her numerous nieces and nephews," a source recently told Entertainment Tonight. "Khloé is just ready to be a mother."

The season 14 finale of Keeping Up With the Kardashians will air on Sunday, March 4, 2018 at 9 p.m. on E!
