Beast Industries, the media conglomerate behind the popular YouTube channel MrBeast, is facing a federal lawsuit filed by a former employee who alleges years of sexual harassment, gender discrimination, and wrongful termination. The lawsuit, filed by Lorrayne Mavromatis, claims she was demoted and subsequently fired shortly after returning from maternity leave in 2025.

Mavromatis, who was hired in 2022 as the head of Instagram for Beast Industries, alleges that she experienced a hostile work environment and was subjected to sexual harassment by company leaders, including former CEO James Warren. According to the complaint, Warren made her attend one-on-one meetings at his home where he commented on her appearance and dismissed her concerns about unwanted advances from a male client, reportedly telling her she should be honored by the attention. The lawsuit also claims that when Mavromatis inquired why MrBeast (Jimmy Donaldson) would not work with her on certain projects, she was told her appearance had a "sexual effect" on Donaldson and that he "gets really awkward around beautiful women."

The suit further details instances of alleged gender bias, including male executives mocking female contestants on "Beast Games" for lacking feminine hygiene products and Mavromatis being told to "shut up" by a male colleague in a staff meeting. She also claims that a company document titled "How to Succeed in MrBeast Production" included statements like "It's okay for the boys to be childish" and "No does not mean no."

Mavromatis formally complained about the alleged harassment and hostile work environment to the company's then-head of human resources, Sue Parisher (Donaldson's mother), in November 2023. Following her complaint, she claims she was demoted to a less significant role. The lawsuit states that Beast Industries did not adequately inform her of her rights under the Family and Medical Leave Act (FMLA) before she took maternity leave. She alleges she was pressured to work even while in labor and shortly after giving birth. Less than three weeks after returning to work, she was terminated, with the company reportedly telling her she was "too high caliber" for her demoted position.

Beast Industries has vehemently denied the allegations. A spokesperson for the company called the lawsuit a "clout-chasing complaint" built on "deliberate misrepresentations and categorically false statements." The company asserts it possesses extensive evidence, including messages and documents, that refute Mavromatis's claims and stated they "will not submit to opportunistic lawyers looking to manufacture a payday."

The lawsuit accuses MrBeastYouTube, LLC and GameChanger 24/7, LLC of violating federal law, including FMLA, and North Carolina state law. Mavromatis is seeking damages for wrongful termination, intentional infliction of emotional distress, and retaliation.
