Khloe Kardashian, the 39-year-old mother of two, recently joined the SHE MD podcast and revealed that she had Tristan Thompson take multiple paternity tests after she realized Tatum looked more like her brother, Rob Kardashian, than herself and Tristan.

Kardashian joked, “Because he was an IVF baby or surrogate baby, I was like, ‘Rob, have you ever donated sperm somewhere? I made Tristan do three DNA tests for Tatum. He was so offended and I’m like, ‘He doesn’t look like me.’”

She continued, “In this family, that would not surprise me but that would be so disgusting. But I remember [my doctor] was like, ‘You’ve already done a DNA test!’ I go, ‘I need to do another one, I need to figure it out.’”

Khloe and her sister Kourtney love that Tatum looks like their brother Rob spit him out. It makes them feel closer to their late father, Robert Kardashian.

“My son is one-and-a-half, and he’s sarcastic. My dad had a really dry, silly, just crazy sense of humor and there’s glimmers of my dad in Tatum and I’m like, ‘This is so freaking weird.’ But it’s just how God works and I love it.”

Even with the jokes about Tatum not looking like Thompson, she doesn’t want the critics to come for him. “My ex Tristan is an incredible father, and I don’t want this to be like a bashing thing. He did make mistakes, but … he’s the nicest guy and we get along so well now," she said.
