Sidney Barney, Tamra's daughter with ex-husband Simon Barney, posted a lengthy message about her mother on Facebook on Monday, ripping her for putting "herself, her fame, her reputation, and her bank account before me."
Rossi caught wind of the Facebook post and commented on the thread saying, "You have no idea how your brave words are helping so many who have been wronged by your mother's manipulation and lies as well...so thank you for being brave enough to speak the truth. I am so sorry your mother and your family is going through any of this, especially publicly, but continue to stay strong. Your morals and strength are commendable and inspiring."

Judge -- who has been creeping in the comments of her daughter's post as well -- shared a screen grab of Rossi's note on her own Instagram page with a (now deleted) message to her former co-star.
"I usually don't give this troll any attention because it's exactly what she wants. But after years of her bashing me and now reaching out to my daughter I must say. Gretchen you are the biggest piece of shit I've ever met. Move on with your sad empty childless life and stay out of mine you thirsty wannabe," she said.
"You are obsessed with my life and I haven't even seen or spoke to you in 5 years," Judge continued. "#MoveOn 👋 You have NO IDEA What my family is going through or what the truth is, Nor do you care. It's just an opportunity for you to get your name in the press. #obsessedfreak. Funny you of all people should be talking about morals 😂. You have none!"
"So sad & always claiming everyone else lies," Rossi clapped back on Twitter.
Judge and Rossi have been feuding for years, in a battle that's raged on even after Rossi's exit as a regular on the Bravo series in 2013.
