Tristan also shared a picture with Amari, which showed him sitting alongside his younger sibling.

‘Happy birthday to my sweet baby brother Amari! I love you forever! We Miss you mommy,’ he captioned the post.

It was revealed on the season three finale of The Kardashians that Tristan’s ex Khloe, Kim Kardashian and Kris Jenner all flew to Toronto with Tristan on Kim’s private jet, and that Tristan and Amaria moved in with Khloe, but she insisted they’re not back together romantically.

Andrea was the sole caretaker for Amari, and when she passed away, Armani was put into Tristan’s care, which meant moving him to Los Angeles, where Tristan lives.

However, in an unusual twist of fate, both Tristan and Amari actually moved in with Khloe, after a mishap with Tristan’s house that was being renovated.

Khloe revealed in confession during the finale, ‘Tristan has a house he’s doing construction on and he’s been renovating. 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.’

Khloe confirms in confession, ‘Tristan and I are 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.’

She added, ‘Tristan is the father of my kids, you know. I’ve lost my dad, and my dad was like a fairy tale parent, but still I can’t wrap my head around losing my mom, and 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.’

Khloe added that Amari has been, ‘having more seizures than normal because he’s just…’ as Tristan finishes, ‘adjusting.’

Khloe adds in confession, ‘I’m grateful that I’m strong enough and brave enough to be a support system for someone else that has no other support system right now. You don’t have to treat me right for me to treat you right. It’s not the way I was raised.’

Tristan says, ‘Thank you so much, especially from me and my family, I don’t know what I would do without you guys right now, like coming to my mom’s house and packing up and going through photos and cleaning up her condo and getting Amari for the funeral. Like, you guys are like so busy, you guys have so much business going on, like, honestly, like, I don’t know, like, I just hope God continues to keep blessing you with everything you guys want, and that’s what my mom would want for you guys, so seriously, thank you,’ as Kris starts wiping tears away.

Kris adds, ‘You know, your mom had a lot on her plate and to be able to be Amari’s sole caregiver like really affected me so much, and that just broke my heart because Amari doesn’t know what’s going on and then all of the sudden you’re just stripped from the caretaker you had your whole life. I just feel so lost for him because he’s probably just wondering where his mommy went and it breaks my heart.’

Kris adds in confession, ‘Tristan has definitely made some mistakes and he’s definitely messed up, but at the end of the day, he’ll always be part of our family and we will be there for him no matter what.’

Tristan adds, ‘But as a son it makes me proud that I know like my mom like, her time on Earth like, you know, she helped a lot of people and she’s remembered for a lot of great things, you know.’
