Khloé Kardashian Is 'Worried' About Lamar Odom, Says Source, 'but He Refuses to Listen'

For nearly three months, since Lamar Odomleft the hospital after his October overdose, Khloé Kardashian has been the former athlete’s primary support system, in more ways than one.

“Khloé supports Lamar financially in every way,” says a Kardashian insider. That includes springing for the rent on Odom’s $3 million Calabasas pad and footing the bill on his nearly three-month hospital stay.

But now, Odom is testing the limits of Kardashian’s generosity. The former Los Angeles Laker went out drinking with friends on March 26, the day before he celebrated Easter with the Kardashian family. (Consuming alcohol is especially dangerous for Odom given the fragile state of his kidneys following his overdose).

Now, “Khloé is very worried about Lamar and his behavior,” says the source. “But Lamar refuses to listen to her. He actually said to her, ‘Nothing will happen to me. Look how I survived the last time.’ “
