ET's Cameron Mathison chatted with the reality TV star inside her new office inside New York City's Trump Tower on Thursday, where she opened up about Lamar's health. The former NBA pro is attending Kanye West's album release party and Yeezy Season 3 fashion show
at Madison Square Garden on Thursday night, marking his first public appearance since he nearly lost his life
in October after he was found unresponsive at a brothel in Nevada.
"Kanye invited him to come, and it's a big deal for him to be able to come," Kris explained. "I'm excited. For him to have this, you know, this is a milestone for him to be able to travel. So, baby steps. But this is a big one. This is a huge step for him."
Kris added that the Kardashian-Jenner family has been "very careful" about Lamar's recovery -- especially his estranged wife, Khloe Kardashian
, whom Kris calls an "angel" -- but believed he was "ready" to come on this trip.
"It's a really short [trip]," she said. "I think it's a great thing for him to be with the family, and come out and do something that we're all a part of, and he really wanted to support Kanye. He really wanted to be here for him, because Kanye was very instrumental in part of his recovery."
"Kanye would go to the hospital and play him music
, and that's what he really, really responded to," she continued. "He was amazing. Lamar started rapping again before he could talk. Isn't that wild?"
"She's a very realistic girl," Kris told ET. "So, when he was going through some dark times, Khloe sort of braced herself, you know? But she's the strongest girl in the world. So, I said to her, 'I'm now changing my medical directive because of you and the way you were with Lamar.' If anything ever happens to me, I want Khloe there! Because she's amazing. OK, Kourtney, you're out. Khloe's in!"
All jokes aside, Kris really did find Khloe's nurturing side "amazing."
"She just really, you know, nursed him right back," Kris continued. "Every one of my kids really, really amazed me at their strength and at the way they were so selfless about just dropping everything."
So will we ever get to call Khloe and Lamar an official couple
again? According to Kris, maybe!
"I think it's no secret that that's probably right out there, written on my forehead or something," she gushed. "Yeah, I mean, I always want my kids to have a happy ending. All of them. And I consider Lamar, he's one of my kids. So, I fall in love with anybody my kids, you know, bring to me and we have as part of our family. They'll always be family, so I always want there to be a happy ending."
As ET previously reported, Lamar and Khloe landed in New York City
early Thursday morning after taking a red eye from Los Angeles. In photos obtained exclusively by ET, the two were seen entering a hotel.
