The 'Keeping Up With The Kardashians' star has revealed she urged her older sibling not to walk down the aisle with the professional basketball player because he's a "f***ing loser".

She said: "There's a ton of times that like you know I've told my sister the truth and she didn't believe me ... like when she wanted to marry Kris Humphries. I was like, 'He's a f***ing loser. Why are you marrying this f***ing dog?' But she didn't have to hear me and that's OK. But the fact is I said what I had to say."

Meanwhile, the 35-year-old television personality previously revealed she thought her career was "over" when she divorced Kris.

She added: "At the time when I was going through the divorce I did say to everyone, 'You guys I think our careers are over. I hope you've saved your money. And now we'll just continue to do our clothing stores and continue to do what we started off doing before the show. I totally thought it was over.

"I was being very paranoid. I just took some time off and the time was really good for me. I cancelled everything. I had a book tour, I had a fragrance launch, I had everything that you could possibly imagine and I just cancelled it all and I took time for me."
