The 38-year-old rapper - who has children North, two, and Saint, four months, with wife Kim Kardashian West - admitted he would have felt uneasy running the risk of people knowing he was watching x-rated films while living with his late mother Donda and then mother-in-law Kris Jenner.

Speaking on 'Kocktails With Khloe', he admitted: "I've never watched porn with the sound on.

"Well...I lived with my mom in high school then I lived in my mother-in-law's house...there's kids next door and stuff."

He jokingly added: "I am all about the storyline."

Elsewhere on the show, Kim revealed the 'Bound 2' hitmaker is desperate to have more children, despite knowing she had suffered with a string of health issues during her previous pregnancies.

Asked if they want more kids, Kim said: "I said no way. I was so set on my two kids and how happy I was with my life the way that it is, but Kanye has been mentioning it every single day lately for the past 10 days."

Khloe asked: "You've been counting the days?"

Kim replied: "Yeah. I'm like, 'Why is he doing this to me?!'

"It would be a really dangerous environment for me if I were to get pregnant again."

The 31-year-old host then asked her older sister if she would use a surrogate, prompting Kim, 35, to admit Khloe, her other sister Kourtney Kardashian and even her friend Chrissy Teigen - who gave birth to daughter Luna last week - had offered in the past.

The news came as a surprise to fellow guest John Legend, who is married to the 'Lip Sync Battle' star.

But Kim insisted: "Chrissy, I have it in an email!!"
