According to TMZ, the 36-year-old basketball player visited the Beverly Center with a friend, but while his pal shopped for shoes, Lamar went to a bar within the mall and ordered the same type of booze he had been drinking when he collapsed, spoke with a few women and, after racking up a $60 bill, left.
That night Khloe simply tweeted: "Hummmmmm... People disappoint."
He told Kourtney Kardashian he had had "real in-depth dreams with people who passed on".
Khloe added: "I think he went to Heaven from the conversations he has with me."
And the 31-year-old beauty admitted she hoped Lamar would look after himself more following his brush with death.
She said: "I kinda want him to be a little more afraid.
"Bad things can happen if you go back to that life. This is, like, a second chance."
At the time, she tweeted: "I hate this feeling.... Helpless."
It was recently claimed Khloe is keen to press on with her divorce from Lamar, having put proceedings on hold while he was hospitalised, now that he has started drinking again.
However, she is concerned at how finally ending their marriage would affect him and she is experiencing a "tremendous amount of guilt".
Despite his past problems, Lamar is said to be adamant he doesn't need rehab, and visiting bars is just him trying to live a normal life, but his estranged wife and her family are certain that isn't the case, having experienced the same situation with him multiple times in the past.
