Scheana Shay is taking responsibility for her error.

The “Vanderpump Rules” star offered her opinion on her coworker Tom Sandoval’s “s–tty” lawsuit against his ex-girlfriend Ariana Madix, stating that she regrets their friendship being maintained following the infamous Scandoval drama that aired in Bravo’s Season 10.

“Tom Sandoval: not the best thing to do after doing something really bad. What the heck are you thinking, anyway? In a Wednesday Instagram Story video, Shay stated.

“Tom Sandoval — s–t thing to do after a s–tty thing you already did. Like, what are you thinking?” Shay said on her Instagram Story. Bravo

She continued, “This is not someone I want to be friends with. This is not who I align my values with. Call me a f–kin’ idiot, okay? I said it at the finale, ‘Don’t make me look like an idiot.’ Welp, you did.”

The “Good as Gold” singer, 39, continued her “rant” by calling Sandoval’s move “cruel” and “vile.”

“I think it negates any remorse that you tried to show at the reunion,” she said.

“Suing Ariana, it’s like, y’all were together for like a decade. You shared a mortgage. You shared passcodes. She knew your password. So, this invasion of privacy? F–k off,” Shay added.

“I said it at the finale, ‘Don’t make me look like an idiot.’ Well, you did,” she added, referencing her previous conversation with Sandoval at the “VPR” reunion. Nicole Weingart/Bravo

Sandoval filed his lawsuit against Madix, 39, on Tuesday — more than one year after it was revealed that he had cheated on her with their then-mutual friend Rachel “Raquel” Leviss.

The Schwartz & Sandy’s founder is accusing her of “obtain[ing] access” to explicit videos of Leviss on his phone without “authorization or permission.”

He also claims that she made “copies” of the footage and “distributed” them to Leviss and “third parties.”

Madix’s lawyer, Jordan Susman, responded to the suit in an exclusive statement to Page Six, calling Sandoval “abhorrent” for “continu[ing] to torment” his ex-girlfriend.

“For Mr. Sandoval to go from begging Ms. Madix for forgiveness to blaming her for his wrongdoing speaks for itself,” Susman said. “He has clearly learned nothing and believes it necessary to continue torturing Ms. Madix in a vain effort to rehabilitate his image.”

The filing comes months after Leviss, 29,  filed a complaint against Madix and Sandoval in February for revenge porn, eavesdropping, intentional infliction of emotional distress and invasion of privacy.

Sandoval’s attorney responded to Leviss’ suit, calling it “a thinly veiled attempt to extend her fame.” Bravo

She claimed the intimate FaceTime calls between her and Sandoval, which showed her “in a state of undress and masturbating,” were filmed without her consent.

In response, Sandoval’s attorneys claimed that the intimate videos were “created by Leviss and published by Leviss to Sandoval via a consensual exchange on FaceTime, i.e., ‘their video calls.’”

“Based on Leviss’ own allegations, Sandoval merely saved private copies of the videos that Leviss had filmed and shared with him,” his lawyers argued.
