Khloe K struggling to divorce estranged hubby Lamar Odom

Khloe Kardashian has been unable to meet with her estranged husband Lamar Odom to finalize terms of the divorce with their lawyers.

Sources close to the reality star asserted that the former pro basketball star isn't responding to calls from the 30-year-old actress or her attorney and has also been keeping a low profile lately, TMZ.com reported.

Lamar had once said that he wasn't convinced that the TV personality would see the divorce through.
