The 59-year-old reality TV personality recently ended her 23-year marriage to Bruce, 65, but remains keen to see him deny rumours of a sex change, which have been increased since he was seen sporting nail polish and growing out his hair.
A source revealed: ''Kris has been pressuring Bruce to issue a statement about ongoing sex change rumours, and she wants it to be a very strong denial.
''She believes that putting out a statement would stop these ongoing rumours, and doesn't understand why Bruce won't do it.''
Last week, InTouch magazine's front cover showed an edited picture of the former Olympian wearing lipstick, blusher, and a silk scarf.
But while Kris - who has two children with Bruce, Kendall, 19, and Kylie, 17 - is eager to end the speculation, her former husband is apparently unwilling to speak to the press.
The source told Radar Online: ''Whenever the subject comes up, Bruce just shuts her down. This is extremely sensitive for Bruce, and it's his choice not to address it.''
