Khloe Kardashian has hit back at allegations her husband has a serious drug problem.
The 29-year-old reality TV star is furious about reports Lamar Odom has been battling an addiction to ''hard-core recreational drugs,'' including OxyContin, also known as ''Hillbilly Heroin'', and crack cocaine, for two years and rumours he sought treatment in a San Diego rehab clinic for three weeks in August 2012.
The 'Keeping Up with the Kardashians' star wrote on Twitter on Sunday (25.08.13): ''Really hard to sit here and listen to people talk s**t about my family! F**k you and shame on you! I'm too protective for this s**t!''
But sources told gossip website TMZ.com that Khloe and her family are still very worried about the Los Angeles Clippers star, 33, who allegedly vanished on Friday (23.08.13) and hasn't been seen for 72 hours.
Insiders said that the family are concerned he is hiding out somewhere while doing drugs.
Khloe was previously reported to have kicked Lamar, whom she has been married to for four years, out of their house in Los Angeles on Wednesday (21.08.13) following a failed intervention.
A source previously said: ''Lamar does not want to go to rehab because pre-season training camps are just around the corner.
''He just doesn't care about anyone or anything right now. He has had it with the Kardashians and just wants to be left alone. Everyone is very, very, worried about him.''
Lamar, whose mother died when he was 10, previously revealed that his father Joe Odom was a heroin addict.
He said: ''I witnessed things that a 10-year-old definitely wasn't supposed to see... It's hard for me to speak up on it and get it through to Khloe because she grew up so different.''
