We only recently found out the name of Khloé Kardashian’s son with ex Tristan Thompson—she revealed it on the first episode of season three of Hulu’s The Kardashians, even though her BFF Malika Haqq let it slip on Instagram a short time before. And, while we assumed Tatum Robert’s last name was Thompson, according to a new report, we learned it initially wasn’t—his surname was Kardashian.
Per Page Six, though he is now Tatum Thompson (his older sister, True, also carries her father’s surname), originally he was a Kardashian. Sources also revealed that Tatum, who is now 10 months, was originally listed as “Baby” as Kardashian took her time to name him. Apparently “Baby” is what was listed, as the State of California doesn’t have Jane or John Does.
