The whispers started when Bruce rented a home in Malibu, which is about 20 minutes away from where Kris lives in Calabasas.
Although the family has denied that Kris and Bruce are having marriage problems, Kris' sister Karen Houghton is now singing a different tune.
Regarding her sister and Bruce, Karen tells In Touch that they "are separated" and that Bruce has already sought out a lawyer.
To make matters worse, Karen says she's heard that Kris flirts with Kourtney Kardashian's boyfriend Scott Disick and Khloe Kardashian's husband Lamar Odom "when she's drunk."
While Karen doesn't deny that Kris has been good to her, showering her with expensive gifts and such, she says that the Kardashian matriarch is "crazy and controlling."
Karen did attend Kim Kardashian's baby shower, but something tells us she might not be invited to the next family event.
