Khloe Kardashian forced ex-boyfriend Tristan Thompson to take 3 paternity tests to prove he is the father of their son, Tatum.
Khloe, 39, expressed concern that Tatum looks a lot like her brother, Rob Kardashian, 37.
She feared that her own brother might be the biological father of her son.

Khloe and Tristan also share daughter True Thompson, 6.
Tatum was born in July 2022 via a surrogate and in-vitro fertilization using Tristanโs sperm and Khloeโs egg.
However, Khloe was concerned that there may have been a mixup at the lab.
On the latest episode of the โSHE MDโ podcast with Dr. Thais Aliabadi and Mary Alice Haney, Khloe said, โI made Tristan do three DNA tests for Tatum. He was so offended.โ
โMy son looks just like my brother, and my brotherโs one of my favorite people,โ Khloe said. โBecause [Tatum] was an IVF baby or a surrogate baby, I was like, โRob, have you ever donated sperm somewhere?โโ
She continued: โIn this family, that would not surprise me, but that would be so disgusting. But I remember [Dr. Aliabadi] was like, โYouโve already done a DNA test!โ I go, โI need to do another one, I need to figure it out.โโ
Khloe said her sonโs mannerisms are strikingly similar to her late father, Robert Kardashian.
โMy sonโs a year-and-a-half, and heโs sarcastic, and my dad had a really dry, silly, just crazy sense of humor, and thereโs glimmers of my dad in Tatum, and Iโm like this is so freaking weird, but itโs just how God works, and I love it.โ
