Khloe Kardashian opened up about jokingly asking her brother about the paternity of her youngest child Tatum Thompson after the shocking resemblance.

“Because he was an IVF baby or a surrogate baby, I was like, ‘Rob, have you ever donated sperm somewhere?’” Khloe said on the She MD podcast. “I made Tristan do three DNA tests for Tatum. He was so offended. In this family, [Rob being the father] would not surprise me, but that would be so disgusting.”

Besides the resemblance to her brother, Khloe said that Tatum also reminds her of her late father Robert Kardashian.

“My son’s a year and a half, and my son’s sarcastic, and my [late] dad [Robert Kardashian] had a really dry, silly, just crazy sense of humor. And there’s glimmers of my dad in Tatum. I’m like, this is so freaking weird,” she said.

The patriarch died of esophageal cancer in 2003.

How Has Motherhood Been For Khloe With Baby Tatum

The Good American founder welcomed her second child with ex Tristan Thompson in 2022. On The Kardashians, Khloe opened up about how motherhood is and the struggles she's had with a newborn this go-around.

“The first couple months are really wild,” she said laughing. “He sleeps until 4 a.m. every night right now and that's just a godsend because the beginning is really crazy.”

“You just forget how mind-boggling the beginning is, because no one would do it again and again if they remembered how torturous the beginning is,” she shared.

She previously shared on episode three of The Kardashians about how her bonding with Tatum differed with True.

“With True, it took me a couple of days, to be like, ‘OK, this is my daughter and I was super into it,' but just days. With him, it's taking me months,” she admitted to her mom Kris Jenner. “I love him and I love kids, but I definitely still don't have that complete bond, but so many people say it takes time,” Khloe says.

Kris adds, “I think that for you, you've been through a lot. Your emotions are spent on trying to deal with trauma and all the stuff that you've been through and I think you have to remember that. I mean, you have to give yourself a little bit of credit.”

She revealed in the following episode how she has worked on her relationship with him.

“Bonding with the baby has definitely gotten easier,” she said.
