Khloe Kardashian Celebrates Ex Tristan Thompsons Brother Amaris 20th Birthday: Our Sweet Angel

Khloé Kardashian has a touching birthday message for ex Tristan Thompson‘s younger brother, Amari.

“Happy Birthday sweet Amari ♥️,” the Kardashians star, 42, wrote via Instagram on Monday, July 27, alongside several throwback photos. “Some people change the world with their words. You change it simply by being you. Your heart, your spirit, and your light say everything that words never could.”

Kardashian’s post included multiple snaps of her, Amari and Thompson over the years from countless family gatherings. (Kardashian and Thompson, 34, dated on-and-off from 2016 to 2021 and share daughter True and son Tatum.)

“You are one of God’s gentlest reminders of what truly matters. Everyone who knows you is better because of you,” she continued. “Thank you for reminding us every single day how we should be so completely grateful for the smallest of things and what unconditional love, joy, grace, resilience, and gratitude truly look like. We love you more than you’ll ever know. Happy 20th Birthday, our sweet angel.”

Khloé Kardashian split with Tristan Thompson in 2021, but she has remained a part of his brother Amari’s life in the years since. Amari, 19, suffers from Lennox-Gastaut syndrome, a form of epilepsy that prevents him from being able to walk and talk. Kardashian, 41, grew close to him and the rest of Tristan’s family […]

While Kardashian and Thompson called it quits for good in 2021, the reality star has remained close with the basketball player and his younger brother. Amari is nonverbal and suffers from Lennox-Gastaut syndrome and epilepsy.

Kardashian’s mom, Kris Jenner, also gave Amari a sweet shout-out on his birthday.

“Happy 20th birthday to our sweet angel boy, Amari!🤍 You are such a blessing to our family and bring so much love, joy, and light into our lives,” Jenner, 70, wrote via Instagram. “Your sweet spirit reminds us every day what really matters. I am so grateful for all of the special moments we share together and I love you so much. Happy Birthday Amari. 🤍🎂 Lovey Xo.”

Following the death of their mother in 2023, Thompson was granted legal guardianship of his sibling. During that time, Kardashian stepped in to serve as a helping hand to her ex as he balanced taking care of Amari full-time alongside his basketball career. (Thompson, who has played for multiple NBA teams, retired in 2025 after a final stint with the Cleveland Cavaliers, who drafted him back in 2011.)

Khloé Kardashian is not here for any mean-spirited remarks about her ex-boyfriend Tristan Thompson’s 19-year-old brother, Amari. “Last time I posted Amari in his dance class, I heard some ridiculous commentary about how, ‘How is this dance? Does he even know what’s going on?’” Kardashian, 41, said in a video posted to her Instagram Stories […]

“Tristan’s mom passed away a few years ago, we — me, Tristan, my whole family — took Amari back with us to the [United] States,” Kardashian said on a July 2025 episode of her eponymous podcast. “Tristan is in the NBA and he is in a different state, literally, every other day or every few days, and it’s just not conducive for Amari to be on that many planes.”

Kardashian added that she has a lot of love for Amari and considers him to be part of her family.

“California weather is so good for Amari, and I just love having Amari be a part of my family,” she explained, noting that she also employs two caretakers to help her. “We just want to provide Amari with the best, most beautiful life that we know how. And he deserves that.”
