It’s an emotional watch as the former NBA star, who has made a miraculous recovery, is cheered by the crowds at Madison Square Garden as he’s walked to his seat by Kanye.
But no one is more emotional than his estranged wife Khloe Kardashian.
Their roller coaster relationship has continued to make headlines since their split back in 2013.
As they fly back to Los Angeles from the show, Khloe, Kourtney and Lamar discuss his recovery.
"God is good but I really want him to be a little more afraid. You're very rare," Khloe, who halted divorce proceedings following his collapse, says.
Caitlyn, who is also travelling back to LA in their private jet, then asks how Lamar is doing.
"Good, thanks to this lovely young lady," he says while pointing at Khloe.
"She certainly was there for you," Cait replies.
Shifting the subject, they start to talk about Kris' friend, actress Melanie Griffith, who was also at Kanye's show.
Khloe, 31, then points to Lamar and says, "If you're lucky".
"Wait, why did she marry him twice?" Kourtney asks.
"Because they got a divorce and then decided they shouldn't be divorced," Kris adds.
"If you guys ever got married can we just skip the wedding part?" Kris asks.
While Lamar says no, Khloe says she was going to say sure.
"But we're definitely getting out of this marriage because it's been a little tainted. We need to cut our ties and then we can figure it back out," the reality star laughs.
Though since the episode was filmed, Khloe has gone on to post a number of cryptic messages about the state of their relationship, most recently a heartbreaking note about "letting go" shortly after Lamar was pictured out drinking.
"Letting go doesn't mean that you don't care about someone anymore. It's just realizing that the only person you really have control over is yourself," it read.
"Letting go with love takes great strength. We have to learn to stop taking on people's problems as if they are our own. Loving people does not mean we have to carry their burdens and confusions on our back.
"Sadly, you can only express your opinion on a situation. You can't want their life more than they do. This is in fact their life to figure out on their own and in their own time."
The Strong Looks Better Naked author quizzes the 36-year-old about his nerves.
“How was therapy today? You're just chilling right? You don't have anxiety only I do, great."
To camera the reality beauty adds: "I've decided to go to New York with Lamar because I think this is something he truly wants to do, and at the end of the day I want Lamar to be happy. I still feel a ton of anxiety and pressure but if this makes him happy and I can keep him safe, then that's a match made in heaven.
"I'm nervous like this is nerve-wracking you [Lamar] haven't been in public ever. I have more anxiety than you do I'm sure but it's because I don't think you understand."
