The reality TV star says he was the "last to know" that his stepdaughter had split from husband Kris Humphries after just 72 days of marriage last October, though he was aware they had been having problems.
He said: "I found out she was getting divorced by hearing about it on the news and stuff.
"I was the last to know. But I could hear telephone conversations in other rooms happening, and I knew something was up, but I didn't know it was that bad until after."
Though Bruce - who is married to the socialite's mother Kris Jenner - has given Kim advice in the past, he insists he is not getting involved in her current situation because he thinks it is best to stay out of personal matters.
He added to America's OK! magazine: "I'm smart enough to stay out of all those things. I have given them advice through out the years, but in this particular case I kept my mouth shut. I didn't want to ... you don't get involved in love. Just hope for the best."
