Brianna “Bri” Stern, a crypto influencer and creator of the Solana-based meme coin SISTER, has filed a civil lawsuit in Los Angeles County against controversial media personality Andrew Tate. The complaint, which has not yet been made publicly available in court records, accuses Tate of sexual assault, battery, and gender violence stemming from an incident on March 11 at the Beverly Hills Hotel.
Stern, who launched $SISTER memecoin, claims the alleged assault was connected to Tate’s promise to support her project in exchange for her involvement in his own crypto venture, DADDY. She said the two were in a prolonged personal relationship that began through crypto-related dealings.
The lawsuit seeks unspecified statutory and punitive damages. Stern is being represented by Buzbee Law, a high-profile firm also involved in the recent legal actions against music mogul Sean “Diddy” Combs. Tate’s legal team at McBride Law dismissed the suit as “a blatant cash grab” and a “desperate attempt” to leverage his public image.
Stern Details ‘Traumatic’ Encounter Lawsuit

Bri Stern has taken to social media to provide personal context around the alleged abuse. In a detailed thread posted to X , Stern described the emotional trajectory of her relationship with Tate, framing it as one that began with trust and affection but ultimately ended in fear and psychological trauma.
“We met because he needed models for his crypto coin, and promised to help save my crypto coin $SISTER,” Stern said.
Their relationship, which she described as intense and constant, soon evolved into what she called a deep personal bond. “He was my best friend,” Stern wrote.

She detailed what she described as a turning point on March 11, the date of the alleged assault at the Beverly Hills Hotel, noting that Tate’s final words to her before she left the hotel were:
“Shut the fuck up, bitch. You will never backtalk me. You are my property.”
Stern went on to describe the emotional difficulty of leaving the relationship, explaining that despite her lingering feelings, she knew she had to walk away.
She says she sought medical attention and went to the police after leaving, describing the days since as “very difficult and extremely scary.” While Stern declined to publicly detail every aspect of the relationship, she stated firmly that her lawsuit and legal counsel now speak for her.
