She said: "My husband and I have an amazing sex life. So far as the sex tape is concerned, whether or not we've made another… if we have it's never something I want to go public.
"[It's] not something I would want anyone else to see but me and Kanye."
Despite wanting to keep their private life just that, Kim did admit that she and rapper Kanye enjoy 'experimenting'.

She continued: "I am married to an incredible man and let's just say we like to have fun.
"Have we made another? There's nothing wrong with being adventurous, having fun and experimenting. Kanye and I have a very good sex life. What we do privately is private."
Kim also briefly addressed Beyonce and Jay Z 'snubbing' her and Kanye's wedding in Florence earlier this year.
She said: "It was a long way to travel. There was no disappointment on our part. Sometimes schedules don't match. Whatever."

Meanwhile, Kim commented on the celebrity iCloud hack scandal this week, which saw nudes of stars including Jennifer Lawrence leaked.
Kim told Newsbeat: "I think people in general just have to be cautious. I don't have an iCloud account on my phone. I think it's a wake up call for people to make sure they have every privacy setting."
