Khlo� Kardashian Is 'Worried' About Lamar Odom

For nearly three months, since Lamar Odom left 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.
