Khloe Kardashian has revealed that Lamar Odom is "doing great," but his short-term memory is still a struggle.

The 31-year-old reality star joined sister Kourtney Kardashian via FaceTime on The Ellen DeGeneres Show last week for an episode that will air later today, Monday, January 25.

And as her face was beamed into the studio via iPhone, Khloe gave some details about her ex's recovery, and revealed that he's been hanging out with Kourtney's and sister Kim Kardashian's children.

"He’s doing really good. His long-term memory is great. His short-term memory isn’t so good, but, I mean, if I met someone earlier today I probably wouldn’t remember either, so that’s understandable!" she said.

"But he’s great. He’s hung out with Kourt’s and Kim’s kids. He loves family time. So he’s been doing really good. 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."

"We’ve explained to him the situation," Kourtney, 36, continued. "We were told he had four hours to live, so it’s a miracle, really," she added.

"And every day he’ll ask me, 'So what happened to me?'" Khloe continued. "Like, today specifically, he was like, 'How many tubes did I have in me again?'"

"And I’m honest,” she revealed. “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 [that] happened.”
