Her educational journey includes a Bachelor’s degree in Law and an Honours degree in Psychology, both from Stellenbosch University in South Africa. Most recently, she completed a Master's degree in Neuropsychology from the prestigious University of Edinburgh in November 2024. This background shows she possesses a deep understanding of the human mind and behavior, a fascinating contrast to the high-octane, attention-grabbing world of YouTube content creation.

2. The Couple Got Engaged on Christmas Day 2024

The highly private couple made their engagement public in January 2025, revealing that Jimmy Donaldson proposed to Thea Booysen on Christmas Day of 2024. The announcement was met with a flood of excitement from fans who have watched their relationship grow since they first met in South Africa in 2022. While MrBeast's life is usually an open book for his millions of subscribers, the details of the proposal were kept intimate, reflecting their desire for privacy in their personal milestones.

3. She is a Published Young Adult Author

Beyond her academic and streaming careers, Thea Booysen is also a published author. She released her first young adult novel, *The Marked Children*, in 2022. This venture into fiction highlights her creative depth and storytelling abilities, which likely resonate with her online audience and complement her content creation efforts. Her book is a significant entity that establishes her career outside of her relationship with MrBeast.

4. Their Wedding Will Be a 'Very Private' Island Affair

Despite MrBeast's reputation for massive, public spectacles, the couple is planning a deliberately small and private wedding. Jimmy Donaldson has publicly stated that he wants the event to be "very private" and "intimate," with plans focused on an island destination. This decision underscores their commitment to keeping their marriage sacred and away from the intense scrutiny of the global media and YouTube cameras. The intention is to share the day only with close friends and family, a stark departure from the typical celebrity wedding.

5. Thea is an Active Twitch Streamer and Esports Caster (TheaBeasty)

Thea Booysen is a successful content creator in her own right, primarily operating under the alias TheaBeasty. She is an active Twitch streamer and YouTuber, with a niche focused on gaming. Her streams often feature popular titles like *League of Legends* and *The Witcher 3*, as well as card games such as *Gwent*. Furthermore, her expertise has led her to work as an esports caster, demonstrating her deep involvement and authority within the competitive gaming community.

6. They Made a High-Profile Appearance in April 2025

One of the few high-profile public appearances the couple has made since their engagement was at the 11th Annual Breakthrough Prize Ceremony in April 2025. This event, often referred to as the "Oscars of Science," sees them stepping out of the traditional YouTube sphere and into a more formal, intellectual setting. Their presence at such an event suggests a shared interest in fields beyond pure entertainment, potentially aligning with Thea's background in neuropsychology and the couple's philanthropic interests.

7. She is a South African Content Creator

Thea Booysen hails from South Africa, a detail that is central to their relationship's origin story. The couple met while MrBeast was visiting the country in 2022. Her South African roots and international background bring a unique perspective to MrBeast’s predominantly American-centric world. This international dynamic is a key part of their relationship's appeal, showcasing a blend of different cultures and content creation styles.
