Khloe Kardashian: "KUWK' Star Heartbroken Over Lamar Odom?

Khloe Kardashian is heartbroken over the downward spiral that her husband Lamar Odom is engaged in, E! News reported Tuesday.

Sources said that the 29-year-old reality TV star is taking her life one day at a time as it relates to her troubled marriage. The two have been estranged because of Odom's alleged drug problems and reported infidelity. Those in their inner circle believed that a divorce was imminent.

"Khloé gave Lamar an ultimatum: if he didn't get help, she'd end the marriage," the insider explained. "So far, he's ignoring her. The situation can still turn around, but at this point, divorce seems imminent."

Furthermore, the source denied that the Kardashian family has been applying pressure for the marriage to end. They were described as being supportive of whatever the Odom's decide to do.

"Her family is being as supportive as possible," says the insider. "They don't want to argue with her or make her even more upset. They know she's already heartbroken. They don't want to make things harder on her. At the end of the day, whatever she decides to do, they'll go along with it."

Odom has been pictured smiling since sources said he quickly entered and left rehab last week.
