Thea Booysen

Thea Booysen is a South African Twitch streamer, esports caster, and author. She is best known for her Twitch channel TheaBeasty, where she streams card games like Gwent and connects with a community of over 30,000 followers. Booysen also works as an official caster for CD Projekt's Gwent esports circuit, a role that places her among the few women in competitive card game broadcasting. In 2024, her engagement to YouTube megastar MrBeast brought her widespread attention, but her own career, built on deep game knowledge, a law and psychology background, and a self-published novel, sets her apart as a multi-talented creator.[edit]

Thea Booysen grew up in South Africa, though she has shared few details about her early childhood or family. She joined Instagram in 2014, posting photos from trips to London and Paris, hinting at a global outlook early on. Academically, she excelled: she earned an honors degree in psychology and a bachelor's degree in law, a demanding double path that she completed before turning to content creation full-time.

Her entry into gaming came through Gwent, the card game from The Witcher universe. She started playing while it was still in beta, mastering its mechanics long before most players discovered it. That early expertise caught the attention of CD Projekt, the game's developer, who brought her on as an official caster for their esports events. This transition from casual player to professional broadcaster marked the real launch of her career in the gaming world.[edit]

Booysen's breakthrough came when she began casting Gwent tournaments for CD Projekt, a role that gave her credibility and visibility in the esports scene. In January 2022, she posted a beginner's guide to Gwent on her YouTube channel; the video earned over 80,000 views and became her most-watched piece of content. Two months later, she collaborated with MrBeast on a Gwent match for her channel, a move that introduced her to millions of new viewers.

Beyond streaming, she authored a book titled The Marked Children, published sometime between 2022 and 2024. The novel, a work of fiction, added author to her resume. As of 2026, she continues to stream regularly on Twitch, cast Gwent events, and build her brand alongside her fiancé's massive platform.[edit]

Booysen presents a casual, approachable gamer-girl persona on stream, often chatting with fans while playing Gwent or League of Legends. Off-stream, her Instagram and Twitter show a more polished, fashion-forward side. Media coverage frequently labels her as MrBeast's fiancée, but her own accomplishments, esports casting, a law degree, a published novel, give her a distinct identity. Her fandom does not have an official name, but her viewers appreciate her informative, friendly style, especially in her Gwent tutorials.[edit]

Thea Booysen operates within a unique cultural ecosystem where her public identity is inextricably bound to the global phenomenon of MrBeast rather than standing as an independent entity with its own distinct fan rituals or folklore. While she maintains a Twitch channel known for Gwent and League of Legends, her audience largely overlaps with the massive "BeastCrew" that follows Jimmy Donaldson, leading media outlets and fans to frequently refer to her simply as "MrsBeast." This designation serves as her primary identifier, eclipsing any personal moniker derived from her streaming career alone. There are no documented grassroots campaigns, charity drives, or organized fan projects funded specifically by supporters for her individual benefit; instead, high-profile gestures like birthday giveaways appear linked to the broader MrBeast brand infrastructure. Her professional legacy includes becoming one of the earliest experts in Gwent during its beta phase and serving as an official caster for CD Projekt, yet these achievements function as biographical facts rather than legendary moments that have spawned viral internet lore or specific crowd reactions separate from her partner's shadow. The defining narrative of her recent life remains the intimate wedding ceremony held at Richard Branson's private Necker Island in July 2026, an event verified by major international news outlets that cemented her status as a central figure in one of the internet's largest brands. Despite this elevated profile, iFANN has evaluated her current standing and determined that she does not currently hold a placement in the published Global Top 1,000 rankings or any scope-specific top lists. She is currently unranked.[edit]

Her YouTube channel TheaBeasty features content focused on Gwent tutorials and match highlights, reflecting her deep expertise in the game since its beta phase. Public records show she has posted photographs with notable figures including PewDiePie and Justin Timberlake. Her Twitter account, Thea_Booysen, blends fashion updates with professional career announcements. A widely retold story of her rise involves meeting Jimmy Donaldson in person during a trip to South Africa before reuniting online to begin their relationship. The most significant event in her modern biography occurred in July 2026 when she married Donaldson in an intimate ceremony at Richard Branson's private Necker Island, an occasion that generated substantial global media coverage despite its private nature.[edit]

Booysen has not publicly shared details about her parents or siblings. She lives with her fiancé, MrBeast, in North Carolina. The couple does not have children. She has a dog, though its name and breed have not been widely reported.[edit]

Booysen is frequently associated with her fiancé, MrBeast, and her employer CD Projekt. She has also met and taken photos with PewDiePie and Justin Timberlake.[edit]

Booysen began dating fellow YouTube star MrBeast (Jimmy Donaldson) in 2022. The couple met through the online content creation and gaming community. They collaborated on a Gwent video for her channel in March 2022. In 2024, MrBeast proposed, and they are currently engaged. No previous public relationships have been documented. As of 2026, Booysen remains engaged to MrBeast.[edit]

iFANN currently estimates Thea Booysen's personal net worth at $500 Thousand as of 2026. Her income streams are derived primarily from Twitch subscriptions and donations, YouTube ad revenue, and her salary as an esports caster for CD Projekt. Estimates suggest she earns between $2,500 and $5,000 per month from her Twitch activities alone. Modest royalties from her self-published novel The Marked Children contribute to her total financial standing. She does not currently hold major endorsement deals or business ventures outside the sphere of content creation. While the wealth of her fiancé MrBeast is vastly larger, this figure reflects her independent career trajectory in streaming and esports broadcasting.[edit]
