Khloe Kardashian has reportedly changed her baby boy's surname to match his father Tristan Thompson.
Back in July 2022, the 38-year-old reality TV star and her 32-year-old former partner welcomed their second child, a boy named Tatum, via surrogacy.
The mother-of-two didn't reveal her son's first name until last month, during the first episode of the hit Hulu and Disney+ show, The Kardashians.
During the latest season, Kardashian casually dropped his name, telling viewers that she'd decided on Tatum as he joined older sister True Thompson, five. However, it has now been revealed that Thompson wasn’t his initial last name.
According to TMZ, sources said that the 10-month-old's surname was originally legally registered as Kardashian, and PEOPLE claimed that the newborn was listed as "Baby" on the birth certificate until the couple came up with Tatum.
Per California law, new parents can choose whether they'd like their child to have the father's last name, the mother's last name, or a combination of both. However, whatever they decide is permanent, which means that a court order would be needed to alter a last name, as cited by the outlet.
Although no specific explanations were given for the name swap, TMZ reports that it most likely had to do with the fact that the parents had been anticipating their baby boy when news broke that the NBA player had secretly fathered another baby with a woman named Maralee Nichols. This marked the third time he had allegedly been unfaithful to Kardashian.
Further reports stated that Thompson had kept secrets from his ex-girlfriend while they ventured on their surrogacy journey, with the Good American founder revealing that he tried to speed up the process because he wanted the embryo to be transferred before she found out he'd cheated on her again.
"I'm not sure that there is one thing that hurts more than the other. Everything is an act of betrayal, everything is a lie, everything is manipulation. It's deceit," she said during an episode of The Kardashians, per Buzzfeed.
"Did Tristan have every opportunity to tell me? Yes. Was Tristan going to tell me if there wasn't a baby involved? Absolutely not, and that shows a lot about his character. The entire thing is despicable," she added.
Nichols later gave birth to the Basketball player's son, Theo, and later claimed that Thompson was "single and co-parenting" when she first met him at a party, per The Mirror.
The name-change news comes after Kardashian opened up about her struggle to "connect" with Tatum during the latest episode of the reality TV show.
The businesswoman spoke about her journey with surrogacy to her sister Kim - whose third and fourth children, Chicago and Psalm, were born via surrogacy - as well as Kourtney's ex-partner Scott Disick.
Disick - who shares children Mason, Penelope, and Reign with Kourtney - flat-out asked the mom-of-two whether she feels "less connected" to Tatum than she did when she welcomed her daughter, True, naturally in 2018. She nodded and replied: "Mmhmm.
"I definitely buried my head in the sand during that pregnancy. I didn't digest what was happening. So I think when I went to the hospital, I really think that was the first time that it really registered [...] It has nothing to do with the baby. 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,'" she said.
Kardashian also admitted that she felt guilty after the surrogate gave birth to her son, adding: "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 sorta separated. It's such a transactional experience."
She later said in her confessional: "I wish someone was honest about surrogacy and the difference of it. It doesn't mean it's bad or good - it's still great, it's just very different."
