Lisa Vanderpump is breaking her silence about those "Vanderpump Rules" cast firings. The reality star took to Instagram to address Stassi Schroeder, Kristen Doute, Max Boyens and Brett Caprioni getting the boot from the hit bravo show over past racist behavior. "Over the past two weeks, many have been brought to my attention, of which I and many others were previously unaware. It was necessary for me to be quiet until now, until decisions had been made. Now I can freely speak from the heart," the 59-year-old wrote.
