Los Angeles: Reality TV star Khloe Kardashian and her estranged husband Lamar Odom are reportedly no longer on talking terms as their relationship continues to turn sour. Earlier last month, Khloe filed for divorce for the second time after calling it off to dedicate her time to help the former NBA star get back to full fitness after he was admitted to a hospital after collapsing in a Nevada brothel last year. A source has now claimed the former couple can barely even speak to each other after Lamar was spotted drinking again in public, reports people.com. "It was her decision. The times she went to see him recently, he was pretty messed up. She is sick of it. She feels like she has done everything she can and it is just ridiculous at this point," the source said.
