Kris Jenner has said her biggest regret is divorcing her first husband, Robert Kardashian.

The 57-year-old confirmed her split this week from her second husband Bruce Jenner with whom she has two children, Kendall (17) and Kylie (16).

Speaking to New You magazine just before the split news, Kris confessed: ''The one regret, if I had to do it over, would be divorcing Robert Kardashian. But then there wouldn't have been Kendall and Kylie, so that's the way I look at it.

''Everything happens for a reason, and we learn from our mistakes. I thought I was so smart when I was young; I was fearless.''

Kris and Robert were married from 1978 until 1991 and had kids Kourtney, Kim, Khloe and Rob together.

Robert Kardashian was best known as O.J. Simpson's defense attorney during his 1995 murder trial.

The reality star went on to compare her only son, Rob, to his father, who passed away in 2003 from oesophageal cancer just eight weeks after his diagnosis.

She said: ''My son is identical to his father, Robert - they look alike, act alike and have the same mannerisms. It's an amazing reminder of what an amazing dad Robert was. He was a great husband and a good person.''

Kris believes her daughter Khloe, who is currently experiencing marital problems with her husband Lamar Odom, is the most similar to her.

She explained: ''Khloe is exactly how I am in the way she likes to nest and cook; the way she is with everything in her home - even the way she makes a bed and sets a table.''
