The reality star revealed that her estranged husband is doing "really good" after he was found unconscious in a Nevada brothel in October.
"His long term memory is great," she told host Ellen DeGeneres. "His short term memory isn't so good, but I mean if I met someone earlier today I probably wouldn't remember either so I mean that's understandable. But he's great. He's hung out with Kourt's and Kim's kids. He loves family time.
"I think it makes him feel good to be around everyone too and to just be in a happy environment over obviously where he was," she continued.
The sisters also revealed that they've been explaining the situation to the former Lakers player, including that he "had four hours to live," according to Kourtney.
"And every day he'll ask me so what happened to me," Khloé added. "Like today specifically, he was like how many tubes did I have in me again? And I'm like I don't know what's too serious to tell you, but I'm honest. I'm like well just a lot I didn't count, I don't know. But it's good that he wants to know these answers. Before he didn't want to know he wasn't ready to know. So it's great that he's at the point that he's ready to know everything happened."
However, the interview, which will air on Monday, didn't just focus on Odom. DeGeneres also grilled Kourtney on the Kardashian-Jenners' love life, including her fling with Justin Bieber.
When asked if she's "really dating" the pop star, Kourtney said that the pair are "friends," but wouldn't go into further detail, despite DeGeneres joking about her coy smile.
As for the family's other are-they-or-aren't-they romance – Kendall Jenner and Harry Styles – Kourtney revealed that she had not met the One Direction singer, although she agreed he "is good looking." However, Kourtney stopped short of directly calling the pair a couple.
