The two women were axed for their treatment of a Black former costar, Faith Stowers, while the men were let go after racist tweets using the N-word were exposed.
While Brett and Max's tweets were referenced during the reunion -- in which Lisa also defended her decision against initially firing them -- Vanderpump says she was "previously unaware" of some of the cast's behavior.
"Over the past two weeks, many things have been brought to my attention, of which I and many others were previously unaware," she began. "It was necessary for me to be quiet until now, until decisions had been made. Now I can freely speak from the heart."
"As we’ve seen such devastating sadness that has played out globally, we all have a part to play to create a kinder, more just society," she continued. "My hope is for this generation to treat each other with respect and humanity, and realize that actions have; and should have, consequences."
"I love and adore our employees and I am deeply saddened by some of the lack of judgment that has been displayed," her statement went on. "As many of you know, after watching me for 10 years, I have always been an equal rights activist and ally - my family, my businesses and I condemn all forms of cruelty, racism, homophobia, bigotry and unequal treatment. We've never tolerated it in the workplace or our lives."

Regarding the very white staff, she said that "while you only see a fraction of our employees on the show, a specific friend group, across all of our companies, we have always been a very diverse group of people - every color, ethnicity and sexual orientation."
"Most of our employees have worked for us for over a decade, and we have become a family; one that embraces and celebrates each other’s differences," she wrote. "I am proud of the inclusive company that we've created. We will continue to embrace diversity as one of our greatest strengths, and I'm excited to give you deeper look into the multi-faceted fabric of our company in the future."
She ended her post by saying the world "needs to move forward with a kinder generation."
"Everybody deserves to feel safe, heard and appreciated in their communities," she concluded. "So much of what has transpired in the world is not right, fair or acceptable. We all have work to do to create a society we can be proud of and I hope as we venture forward, we strive to live in a world where kindness and compassion are our highest values. Thank you for listening, love Lisa."
All four were terminated by Bravo on Tuesday and will not appear in Season 9 of the series. The decision came after Faith Stowers did an interview in which she accused Stassi and Kristen of reporting her to the police for a crime she did not commit.
Both Schroeder and Doute had already previously admitted to doing as much and made headlines at the time, but Stowers' interview brought the behavior back to light and sparked major backlash.
As for Max and Brett, Andy Cohen actually asked Lisa during the reunion why she initially decided to keep them on the show after the tweets came to light. She defended her decision to keep the boys, saying, "If I fired every one of you that have made mistakes, it doesn't matter to what degree, probably none of you would have a job."
