Khloe Kardashian 'definitely' made a sex tape with Lamar Odom

Khloe Kardashian has admitted she 'definitely' made a sex tape with her estranged husband, Lamar Odom.

The 'Keeping Up With the Kardashians' star admitted she and the sportsman - who she split from in December 2013 but still hasn't divorced - got intimate on camera, but she's taken precautions to keep the raunchy footage private.

She said: ''I've definitely recorded myself having sex with my ex-husband, but not like talking to camera. ''Do you remember those little cameras... they were little video cameras that you put in your pocket? That was my jam for a moment.''

Asked by 'Watch What Happens: Live' host Andy Cohen if she still has the tapes, she said: ''I do. In my safe.'' Khloe's sister Kim Kardashian West shot to fame largely thanks to a 2003 sex tape which she made with then-boyfriend Ray J, which was made public in 2007.

And the 'Kocktails With Khloe' star admits she has ''no idea'' how her sibling - who is now married to Kanye West - will explain the infamous footage to her children North, two, and Saint, six weeks, when they are older.

Asked by a caller how she'll explain the tape, she said: ''Good question but I don't know. That's what moms and dads do, I don't know, to their own kids. ''I have no idea. That's what moms and dads have to do. Do they all? I don't know.''

Elsewhere on the show, Khloe - who is now dating James Harden - dismissed speculation Justin Bieber had slept with any of her sisters, despite him previously being romantically linked with Kourtney Kardashian and Kylie and Kendall Jenner, and played a game of 's**g, marry, kill' with her siblings' partners and former partners as choices.

She said: ''I'd marry Kanye. Oh God, this is weird. S**g Scott [Disick, Kourtney's ex-partner], kill [Kylie's boyfriend] Tyga, and there's no reason why.''
