10 months after giving birth, the name of Khloé Kardashian and Tristan Thompson's son has been revealed.

According to US Sun, they named their son Robert Tatum.

"It was discussed whether it should be Robert Tatum or Robert Tatum," a source told the paper. Some in the family were more inclined toward the name Robert because it honors her father and her brother, [Rob Kardashian].

Khloe's father, Robert, died in 2003 from cancer.

"Khloé wanted a name that was somewhat unusual but not too over the top and also started with the letter T," the source explained.

Khloe confirmed on a September 2022 episode of The Kardashians that her son's name "would start with T," like daughter True and father Tristan.

She and Tristan conceived their son through a surrogate. Tatum Robert was born in August 2022. The former couple are also parents to a 5-year-old daughter, True.

As for the Khloe-Tristan relationship, the star of "The Kardashians" and the basketball player were connected in August 2016 and finally separated in December 2021, after successive betrayals of the former partner.
