The 'Keeping Up With The Kardashians' star is reportedly concerned about her estranged husband as he recovers from a drink and drug binge last October.

A source told PEOPLE magazine: "Khloé supports Lamar financially in every way. Khloé is very worried about Lamar and his behaviour. But Lamar refuses to listen to her. He actually said to her, 'Nothing will happen to me. Look how I survived the last time.'"

Meanwhile, the 31-year-old television personality previously revealed she still loves Lamar with "every fibre of her being".

She gushed: "We're not back together. We're not at all. I love him with every fibre of my being ... but we were married and I shared that union with him. I didn't want for our divorce to happen, but it happened for many reasons and that doesn't mean I just forget about this person.

"I still believe in my vows of being there for him. I know it's confusing. it's very confusing. It's not a romantic place. It's coming from a place of real care and concern and love. I don't think love just because we're not romantically involved means I can't care about someone. I find that so simple-minded."
