'Stop Lying About Everything': Teen Daughter Of Real Housewife Tamra Barney Lashes Out At Estranged Mom, Calls Her Father — Who Is Seeking Full Custody -- A 'Great Dad'

The mother and child reunion is more than a motion away in the case of Tamra and Sidney Barney.

The plot thickened in their saga Tuesday, as the precocious 15-year-old broke her silence on the ongoing family drama via Twitter, imploring her estranged reality star mom to “stop lying about everything,” involving her children in the social media mudslinging, and assuring the masses that she’s "not suffering."

As RadarOnline.com previously reported, The Real Housewives of Orange County star’s daughter moved out of her mother’s home last October to live with her father Simon, who’s currently in a contentious co-parenting battle with the blonde Bravo bombshell.

Simon Barney, wanting to modify their current custody agreement to have full custody of his teen daughter, said the reality star has been guilty of child neglect, even shirking her duties of making sure the children are bathed and fed while in her stead.

(Mad as a hornet at RadarOnline.com for breaking the humiliating story, Tamra posted a family pic on her Facebook page and defiantly declared, “I even fed my kids afterward and made them take a shower. Imagine that RadarOnline.com online.”)

Barney’s new husband Eddie Judge got in on the act Tuesday, implying Simon was on a cash grab when he asked via Twitter, ”If u need money wouldn't u just ask?

“Why embarrass the kids through all these false allegations? Will this justify u?”

But Sidney Barney was having none of it, countering Judge’s inferences in saying that that if her father Simon — who parted with Tamra more than two years ago — “needed money, he would have gone for child support and not full custody.”

In another comment, Sidney said of her father: "He is a great dad but everyone thinks he is a terrible person because they believe the lies. It's getting old."

The starling comments from Sidney came on the heels of her revelation that she was excluded from her mother’s Hawaiian vacation, — an accusation Tamra told us amounted to “bullsh*t.”
