Kris Jenner -- Bruce Never Talked Transition During Marriage

Kris Jenner was in the dark about Bruce's desire to become a woman during their entire marriage ... this according to sources directly and closely connected to Kris.

Our sources say Kris says Bruce did speak with her 25 years ago about his feelings, but she says he talked about his "tendency" to dress like a woman ... not to become one.

We're told Kris insists the subject never came up again during their entire marriage. She also says she never saw Bruce dressed as a woman during their entire relationship.

Our sources connected with Bruce tell a different story ... that she knew full well he was very conflicted about his gender.

Kris tells our sources the subject of sexual transition did not come up until after they were divorced. In fact our sources say Bruce told the girls about it before Kris.

One other thing ... we're told reports that Kris might take legal action against Bruce if he speaks negatively about her are untrue.
