The lawsuit Taryn Southern filed against Bryan Johnson ended without any ruling on whether her allegations were true. An arbitrator dismissed the case in 2023 after finding that a release-of-claims clause Southern had signed in an employment separation agreement with Johnson’s company Kernel waived her right to sue. Southern was ordered to pay $584,199.16 in Johnson’s legal fees, plus 10 percent annual interest, and the action was formally dismissed with prejudice on December 5, 2023.
Southern, a filmmaker and early YouTube creator, had been engaged to Johnson, the tech entrepreneur behind Braintree and the longevity company Blueprint. She sued him in Los Angeles County Superior Court on October 6, 2021 (Case No. 21STCV36987), roughly two years after their breakup.
What Southern Alleged
The complaint contained eight causes of action, including breach of contract, fraud, unjust enrichment, intentional infliction of emotional distress, and loss of earnings. The prayer for relief sought damages “in excess of one million dollars.”
At the center of the case was a claim under what California recognizes as a Marvin agreement, named after a case involving the actor Lee Marvin. Southern alleged that Johnson had made an express oral or implied promise to share assets and to provide lifelong financial and medical support. She said he repeatedly told her to “stop worrying about money” and promised to “take care of her for the rest of her life,” and that she relied on those assurances when she set aside her own career to work on his ventures.
The backdrop was harsh. Southern had been diagnosed with stage III breast cancer, and by October 2019, while she was undergoing chemotherapy and radiation, Johnson told her to move out of the Venice Beach home they had shared for three years. According to the complaint, he referred to her as a “bad deal” and a “net negative” and offered a $149,000 stipend to leave.
During the relationship, Southern’s work and finances had become tightly bound to Johnson’s companies. In 2017 she signed a full-time employment agreement with Kernel, his neurotechnology startup, at an annual salary of $20,800, and held a $15,000-per-month consulting contract for media and communications strategy. She also directed I Am Human, a documentary Johnson financed that featured Kernel’s technology.
The Separation Agreements That Decided the Case
In early 2020, Southern signed two separation agreements. A personal separation agreement stated that the parties had “entered into no written, oral or implied agreement to pool their earnings or to share in their respective assets” and that “Bryan did not agree to financially support Taryn during their relationship.” Under its terms, Johnson agreed to cover moving costs up to $5,000, pay $5,000 per month in rent for twelve months, provide $7,000 per month in financial assistance for twelve months, and make a one-time “producer’s payment” of $70,000.
She also signed an employment separation agreement with Kernel, effective February 7, 2020. That document contained a general release of claims against Johnson and all entities he owned or controlled, a non-disparagement clause, and strict confidentiality provisions. The severance payment was $1,000. Southern’s attorneys later argued she signed both agreements without independent legal representation and under pressure from Johnson.
Those documents ended the case. Johnson’s legal team moved to compel arbitration, citing arbitration clauses in the employment agreements, and the court sent the matter out of open court and into private arbitration. The arbitrator never reached the factual merits. Instead, the arbitrator found that the release-of-claims clause in the Kernel employment separation agreement waived Southern’s ability to bring the suit, meaning the truth of her allegations was never tested. A fee-shifting clause in the same employment agreements produced the six-figure legal fee award against her.
Sanctions and a Second Lawsuit
In July 2023, Johnson filed a motion for sanctions against Southern’s lawyers, who had argued the arbitrator was corrupt. A judge found those arguments frivolous and fined the lawyers $2,500.
On November 13, 2023, Southern filed a second, related action against Johnson and several of his entities (Case No. 23STCV27632), categorized as a general employment matter and alleging violations of California labor laws and breach of contract. It was dismissed with prejudice on December 5, 2023, the same day the original case was formally dismissed. An associated appeal (Case No. B319501) was dismissed in January 2024.
Johnson’s Public Response
Six days after the dismissal, on December 11, 2023, Johnson released a 16-minute YouTube video titled “My Ex-Fiancée Sued Me for $9,000,000” and published a roughly 2,000-word post on X. He characterized the lawsuit as a “#MeToo extortion scheme.” “Their strategy was to inflict maximum pain and suffering on me so that I would pay up privately,” he said in the video. The $9 million figure traced back to an April 2021 pre-suit demand letter from Southern’s lawyers; it did not appear in the court filings themselves.
In the same video, Johnson made an allegation that had never surfaced in any court filing or deposition: that in November 2019 he “feared for his life” after seeing a pair of scissors on a countertop within Southern’s reach, which he attributed to what he called “chemo-rage.” Asked by Vanity Fair reporter Rachel Dodes why the incident was absent from the legal record, Johnson replied, “It was never germane to the court proceedings.” Friends of Southern rejected the account. Julia Price called it “mind manipulation,” and Anna-Marie Wascher questioned the plausibility of Johnson fearing “a 100-pound cancer patient who was ‘within reach of scissors.'”
Johnson also announced he had established a trust for Southern’s medical needs, naming her as the sole beneficiary, and pledged that every dollar of the legal fees she owed him would be routed into it. According to reporting citing an email sent to Southern’s lawyer in 2024, the trust was never funded and was eventually shut down. Neither Southern nor the trust received any money from it.
The NDA Question and Where Things Stand
Southern has said little publicly. A friend told Vanity Fair she is constrained by what the friend described as a “one-sided NDA” that prevents her from telling her side of the story.
The confidentiality provisions that shaped Southern’s case have since drawn broader scrutiny. Johnson has acknowledged using such agreements with more than two dozen people over the past decade. On March 21, 2025, the New York Times published an investigation by Kirsten Grind examining how Johnson used confidentiality agreements at Blueprint. At least three former employees, including Southern, have filed complaints with the National Labor Relations Board challenging those agreements. On March 31, 2025, Johnson’s counsel sent Southern a cease-and-desist letter threatening legal action over public statements she had made about him and about NDAs generally. An attorney representing several former employees filed an unfair labor practice charge the following day, arguing Johnson’s actions violated federal labor law protecting workers’ rights to discuss their working conditions.
The underlying question Southern’s suit posed, whether Johnson had made an enforceable promise of lifelong support, was never answered. It was foreclosed by a release she signed for a $1,000 severance while leaving a job at his company.
