In a FaceTime chat with Ellen DeGeneres, Khloe Kardashian revealed that Lamar Odom is "doing great" but is still having issues with short-term memory.

Hopping on to sister Kourtney's The Ellen DeGeneres Show appearance, the 31-year-old gave some deets about her ex's struggle.

"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.

Khloe also added that Lamar's been spending time with Kourtney and Kim's children. Aww!

Speaking of children -- while on the show, Kourt got asked about her relationship with Justin Bieber. The 36-year-old got pretty coy when the talk show host pressed -- but the mom of three insisted that she and the Biebs were just good friends.

Umm whatever you say!
