Khloe Kardashian has offered an update about her estranged husband Lamar Odom’s condition — and it sounds like he’s making slow but steady strides toward recovery.

While promoting her new self-help book, "Strong Looks Better Naked," at a book signing event on Monday night (Nov. 9), the reality star told "Extra" that Odom has “a long road” ahead of him.

"He’s definitely doing better which is awesome, every day is better," Kardashian said. "He’s off of all machines. He is alive on his own, and no machines are helping him, which is great. But he still has a lot of physical and cognitive therapy to go through, so it’s a long road for him.”

The former NBA player was found unconscious at a Nevada brothel on Oct. 13 following a drug overdose. He was in a coma for four days, with Kardashian by his side, and underwent two emergency surgeries on Oct. 22.

"It’s gonna be a long long time, every day is different,” Kardashian continued. “Some days he’s really strong and some days he’s weaker than the day before because it’s mentally draining — I’m sure — on him.”

Kardashian said she expects Odom to be released from Los Angeles’ Cedars-Sinai Medical Center as soon as he’s able to get around on his own.

"He will try to learn how to walk so that is first,” she said. “When he can support himself on his own, or physically try to walk better on his own, or at least with an assistance, with like a walker, then he will probably leave the hospital and do a lot of cognitive and mental strengthening.”

In the days following Odom’s overdose, it was revealed that he and Kardashian are still married. She later called off the divorce, but told E! News at the same book signing event on Monday that she and Odom are not back together.

"I understand why it's confusing to other people because it's confusing to me, too, but I understand why the media wanted to make it this great love story like that would be wonderful but there are so many more layers that people are forgetting," she explained, adding that her boyfriend, James Harden, has been “really supportive, really understanding.”
