The Keeping Up With The Kardashians star has been supporting Lamar since 13 October, when he was found unresponsive in a Nevada brothel. She was by his side while he remained in a coma and has been a frequent visitor to the hospital since he awoke.
Appearing on Good Morning America today, she said: "He is doing really well. He's finally out of the hospital. He's doing great. But you know, it's a long journey and it's something that he's working really hard on."
"Every day is different. We take every day as it comes. I've learned not to really look into the future too much. I try to live every day as it comes and I'm just thinking 2016 is a good year. My talk show is coming out. We're leaving all the hospital stuff in 2015 and this year is good and positive."
Khloe, 31, reflected on the moment she arrived at Lamar's bedside in Las Vegas last October, saying: "It was really scary. I know when we got to the hospital in Vegas, we were told, you know, there's only a few hours to live and had to make some medical decisions and there were a lot of challenges but he's a fighter and obviously he's here now and he's out of the hospital.
"It was a long stay, almost four months in the hospital, but he's doing great and I mean it's a long journey. It will be a long journey but as long as he's willing to fight it and constantly better himself that's all I could ask for."
She added: "I do believe that we're soul mates but right now that's not even where my head is at. I'm more from like a friend standpoint. I genuinely love him and I genuinely want him to be happy and healthy and all of that, like I would any of my family members or loved ones, so that's at a place where I'm coming from.
"I think people -- they don't understand the severity of everything and that's not even a factor, but knowing or thinking that Lamar was my soul mate before any of this happened, yeah, but things change and life gets in the way and that's okay. And it's all about his health and my happiness and his happiness and right now those are two individual things."
Khloe and Lamar split in 2013 but their divorce has not been finalised yet.
