Los Angeles: Khloe Kardashian was absent from sister Kim Kardashian's birthday party to reportedly be by her estranged husband Lamar Odom's side as he recuperates after collapsing at a brothel in Nevada last week.
The 35-year-old basketball star regained consciousness, three days after hospitalisation.
The Kardashians and Jenner clans gathered to help Kim's celebrating her 35th birthday on a surprise party threw by husband Kanye West on October 21, reported Us magazine.
"Lamar isn't doing that well. He can't stand up by himself. She is still very worried about him and uncomfortable with leaving," a source said.
