We're seriously dying to know why!

The Kardashians abruptly cut ties with longtime stylist Monica Rose, and while the reason why has yet to surface, we're now learning that momager Kris Jenner was the one who initiated the freeze out.

"Kris told her girls in April to cease contact with Monica,” a source dished to Us Weekly.

Almost immediately, the whole family dropped Rose from the payroll and unfollowed her on Instagram, so something serious must have gone down. But what? Our guess is that she tried selling info on their personal lives, but it could be anything!

The truth will come out eventually...
