Kylie Jenner wishes big sister Khloe Kardashian’s baby boy Tatum a happy 1st birthday as she declares he’s her son ‘Aire’s best friend for life’

Kylie Jenner posted a sweet birthday tribute to Khloé Kardashian’s son Tatum on his first birthday.

The Kylie Cosmetics mogul, 25, post a darling photo of two tiny hands holding hands.

She captioned it: ‘Happy belated birthday Tatum. we love you. Aire’s best friend for life,’ and added a white heart.

Kylie’s son Aire turned one in February, while Tatum Thompson turned one on Friday.

The sisters also have daughters, Stormi Webster – who made her debut in her dad Travis Scott’s music video – and True Thompson who are the same age.  

And Tatum also made his debut on his father, Tristan Thompson’s, Instagram this weekend. 

‘Tatum!!’ the NBA star, 33, wrote. ‘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.’

Tristan has been taking care of his 16-year-old brother Amari since his mother’s Andrea’s sudden death in January at age 53.

Armani has epilepsy and is severely disabled and in a weird twist of timing, just as Tristan was taking over his care, his house was undergoing renovations after his roof caved in.

So he moved in with his ex-girlfriend and the mother of his children, Khloé. 

This all played out on the most recent episode of The Kardashians on Hulu.

‘Tristan has a house he’s doing construction on and he’s been renovating,’ Khloé said in a confessional. 

‘He was able to live there during renovations, but we had crazy weather for California, like extreme rain, and Tristan’s roof caved in on his home and caused flooding. 

‘So Tristan and Amari are staying at my house right now, until his home gets fixed.’

‘God does have a plan and God doesn’t want him to be alone right now, and why should he be?’ Khloe says, as Tristan walks in with his and Khloe’s son Tatum in a stroller. 

She continued, making it clear that she and Tristan were not back together: ‘I know it’s hard for everyone to believe, but I love love love Andrea and I love Tristan, I love Amari, and this is what family does. 

‘Tristan is the father of my kids, you know. I know how close Tristan and his mom are, and it’s just heartbreaking, and to be left with the responsibility of another person as well, it’s a lot,’ she explained. 

‘I just think that this is what family does when s**t hits the fan. All you have is your family and Tristan and I are family and we’re gonna be family for the rest of our lives.’
