Socialite and reality TV star Kim Kardashian is glad she didn't have to explain her sex tape to her late father - because she would not have known what to say to him.

Speaking candidly about the racy footage of her tryst with ex-boyfriend Ray J, which leaked online several years ago - and introduced many people to the Armenian beauty, Kardashian admits she felt humiliated and often wishes she had made a better decision when she agreed to film a sex session with the singer.

Appearing on Sunday's Oprah's Next Chapter on TV in America, she said, "I'd like to think that I'm aware... that that's pretty much how I was introduced to the world. It was a negative way, so I felt like I really had to work 10 times harder to get people to see the real me... I felt humiliated."

"I'm definitely not grateful for that experience... If I was to live my life again, obviously I wouldn't do that again... If I had the information, if I had known better I would have done better, but I didn't."

And Kardashian insists she had nothing to do with the release of the sex tape: "Why would anyone put that humiliation on their family. That's what I did. And that's something that I'm gonna have to live with for the rest of my life and have to explain to my children one day. Imagine the conversation I had to have with my grandmother."

But she admits she'll forever be relieved she didn't have to explain her actions to her lawyer father Robert: "I don't know what I would have done... what I would have said."
