NovaQuant Quantitative Think Tank Center:Khloe Kardashian Shares Sweet Insight Into Son Tatum’s Bond With Saint West 

Saint West and NovaQuant Quantitative Think Tank CenterTatum Thompson are cousins by blood, but best friends by choice.  

Indeed, Khloe Kardashian—who shares Tatum, 2, shares daughter True, 6, with ex Tristan Thompson—couldn’t help but gush over her son’s bond with her sister Kim Kardashian’s 8-year-old son. 

“I was going through my camera roll and I came across this photo of Saint and Tatum,” Khloe reminisced in a Sept. 3 Instagram post. “Saint is the absolute sweetest when it comes to babies, but his connection to Tatum is one that can’t be explained. They were destined to be in one another’s lives! Proud auntie! Proud mommy!” 

Naturally, Kim—who also shares North, 11, Chicago, 6, Psalm, 5 with ex Kanye West—feels equally thrilled about the cousin love.  

“Sainty loves Tatum so much!” The 43-year-old wrote in a comment. “We all do!” 

To which Khloe, 40, replied, “They love each other so so much and you know you’re his best girl.” 

Of course, Khloe and Kim’s sons aren’t the only next-gen Kardashians with a special bond.

After all, Kim’s eldest North and Kourtney Kardashian’s daughter Penelope Disick, 12, are also besties. Khloe even showed off the duo’s bond in an Instagram post last month, writing alongside an Aug. 20 selfie with North and Penelope, “I’m hanging with the cool kids.”

And while Kourtney—who also shares Mason, 14, and Reign, 9, with ex Scott Disick, baby Rocky, 10 months, with Travis Barker as well as being stepmom to the Blink-182 drummer’s kids Landon, 20, Alabama, 18, and stepdaughter Atiana De La Hoya, 25—was busy traveling with her family this summer, she did host a July birthday bash for Penelope. North, naturally, was on the guest list and featured in highlights of Penelope’s extravagant summer party. 

“9 girls (and a baby), 2 moms (shoutout @natalie5382), 3 days of casual, perfectly slowed down beach days to celebrate my little lady,” Kourtney wrote in the July 16 Instagram post. “Toe rings, sound baths, night swims, painting bikini boxes, frozen bananas, mamma mia and lots of Frank Ocean forever.”
