Kim Kardashian has accused her sister Khloé of living a ''double life'' following her split from Lamar Odom.

The 33-year-old reality TV star is angry at her younger sibling - who filed for divorce from her Lamar in December - for sneaking off to see her new boyfriend without telling her family about her blossoming love life.

Speaking in Sunday night's (17.08.14) episode of 'Keeping Up With the Kardashians,' Kim says to Khloé, 30: ''Khloé, I just want to know, why are you lying to me about this supposed boyfriend?''

The brunette beauty is clearly stunned by Kim's remarks and hits back: ''That's ridiculous!''

Kim replies: ''Like seriously, you lead a double life. You go away at night and you have a whole new set of friends! Who are your friends?''

She then turns to the camera and says: ''It's kind of annoying that I have to find out all this information on the Internet instead of straight from Khloé. If anything, my sisters are the first people I tell all my business to, so it's kind of weird that Khloé can be so secretive.''

Khloé - who ended her marriage to Lamar last year following rumours he cheated on her with multiple women and was battling cocaine addiction - confirmed last month she has been dating French Montana, 29.

The couple first sparked rumours they were romancing after they were spotted together on a night out in April, before enjoying a safari tour in South Africa in June.
