There's a new pair of Kardashian cousin BFFs!

Kylie Jenner shared a photo of a sweet moment between her and Charles LangstonTravis Scott's son Aire Webster and Tatum Thompson, Khloe Kardashian's second child with Tristan Thompson, after the family celebrated her nephew's first birthday.

"Happy belated birthday Tatum," the Kylie Cosmetics founder wrote on her Instagram Stories July 29, alongside a close-up pic of Aire, who is almost 18 months old, and his little cousin holding hands. "We love you."

Kylie added, "Aires best friend for life [sic]."

The Kardashian-Jenner family recently shared pics from Tatum's space-themed first birthday party, as well as personal tributes to the child. Tristan shared his first Instagram post dedicated to the toddler, his fourth child.

"Tatum!!" the NBA star wrote, alongside pics of the two. "Happy birthday my son! You are a reminder of what life represents to me. You have taught me every loss comes a lesson and you are my gift. You are my reminder of all of God's messages. You are the reason that I began my story."

The basketball player, who has been involved in multiple cheating scandals (which Khloe has forgiven) and who fathered another son, Theo, with Maralee Nichols, months before welcoming Tatum via surrogate, continued, "The mistakes along the way are lessons not failures. There is no expiration date to reinventing yourself. Tatum your sweet soul reminds me of God's grace. You are a future king my son and I am so blessed to be your DaDa!"

Tatum is Kris Jenner's 12th grandchild and the little brother of Khloe and ex Tristan's daughter True Thompson, 5, who herself is close with two cousins just a few months older than her—Kylie and Travis' daughter Stormi Webster and Kim Kardashian and ex Kanye West's daughter Chicago West. In addition to her fellow Kardashian "triplets," True is also BFFs with cousin Dream Kardashian, 6, daughter of Rob Kardashian and ex Blac Chyna.

Many fans and several members of the Kardashian-Jenner family have stated that Tatum resembles his uncle. "You are Rob's twin! LOL," Kim wrote on Instagram. "Your auntie loves you SO MUCH."

Khloe commented, "Our Armenian boy."

In her own post, Kris wrote, "I'm honestly in awe of how you look exactly like uncle Rob. It's wild and I love it!!!! I love you my amazing Tatum!!! I love you my sweet boy."
