Khloe Kardashian took an apparent swipe at rumors she and husband Lamar Odom are headed for divorce. 

Their marriage has been thrown under the media spotlight after several women claimed Lamar cheated on his reality TV star wife with with them.  

The claims were made by Jennifer Richardson and Polina Polonsky, the latter claiming a six-week affair with professional basketball player Lamar and telling Star magazine he had "acted completely available".

Last week, Lamar was pictured loading luggage into his vehicle in Calabasas, sparking reports that the couple, who married in 2009, are living separately. An unnamed source told the Hollywood Gossip that Khloe "kicked him out".

"Lamar is tired of living in hotels and is now threatening to file for divorce because he is tired of the situation. Khloe has given him no indication as to whether or not she wants to work on the relationship and save the marriage," the source said.

Entertainment website TMZ reported that Lamar, 33, was also struggling with substance abuse.  

Khloe took to Twitter to vent some of her frustration over the rumors.

"Really hard to sit here and listen to people talk shit about my family! F*** you and shame on you! I'm too protective for this s***!" she said.

This followed on from a tweet in the last few days telling fans "Your energy is what keeps me going" and another tweet saying "Only the strong will survive".
