Kris Jenner has a medical problem that required her to go to the hospital, and even though they're separated when times get tough her go-to person is still Bruce.
We've learned Kris just went to a hospital in Thousand Oaks -- near her home -- for X-rays and possible tests for an undisclosed medical problem. She was accompanied by Bruce, who we believe came from his home in Malibu to be with her.
Kris and Bruce have actually become closer we're told since their separation, because there's no tension over the relationship anymore -- they're simply close friends and confidantes.
Again ... it's unclear why Kris needed to go the hospital.
