Khloé Kardashian finally reveals name of son with Tristan Thompson: 'His name is Tatum'

The rumors are True!

After many outlets speculated about the name of Khloé Kardashian and Tristan Thompson's son, born in August, Kardashian finally revealed the child's name in the Season 3 opener of Hulu's "The Kardashians."

In the second half of Thursday’s episode, Kardashian, 38, is asked by a producer if she’s named her son.

"His name is Tatum," she shares. "So, Tatum and True."

"Naming a human is really hard," the reality star confesses.

Kardashian, who has shared glimpses of her son on Instagram, adds in the episode that Tatum looks like the star's younger brother Rob, 36. Older sister Kim Kardashian, 42, agrees.

The reality star and Los Angeles Lakers player are also parents to daughter True Thompson, 5. The on-and-off couple called it quits over Thompson’s repeated infidelities.

The new mom also shared how her second pregnancy felt different from her first.

"I definitely buried my head in the sand during that pregnancy," Kardashian says in the episode of her journey having a surrogate for Tatum. She adds that she "didn’t digest what was happening. And so I think when I went to the hospital, I really think that was the first time that (it) really registered."

"And it has nothing to do with the baby," she adds. "It’s just you're like, 'OK, we’re having a baby, and this is my son, and I’m taking him home with me.'

"I definitely was in a state of shock, I think from my entire experience in general," she continues. "I felt really guilty that this woman just had my baby and I take the baby, and then I go to another room. And you’re sort of separated. I felt it’s such a transactional experience because it’s not about him."

"I wish someone was honest about surrogacy and the difference of it," she says. "But it doesn’t mean it’s bad – it's still great. It's just very different."

Kardashian welcoming Tatum has been complicated for other reasons as well.

In January, Thompson confessed on Instagram to fathering a child with another woman only months after he and Kardashian had transferred an embryo to a surrogate for their second pregnancy.

When asked about the hardest moment to film on her new show, Kardashian told USA TODAY ahead of the last season that it was the moment she first heard the news.

"I don't even want to cry," an emotional Kardashian said of the situation in the Hulu show's Season 2 premiere. "Tristan and I are – I don't even know if I want to say Tristan and I. I am having another baby, and obviously it's just really private and I just don't want this to get out right now because I want to protect my mental well-being as the surrogate's, and all of that. It's just been a lot to go through all at the same time."

But with the arrival of Tatum, Kardashian's mood has visibly shifted. Premiere footage showed the mom once more beaming as she held her son in the hospital and introduced True to her baby brother via FaceTime.

"Ever since December, it's been this dark cloud looming over me," Kardashian added in the Season 2 episode. "Every single day I've been feeling depressed and sad and now that my son is here I get to move on and I get to enjoy. It's almost like I get to close that chapter and be done with this trauma and put it behind me."
