YouTuber MrBeast, real name Jimmy Donaldson, has married his fiancée Thea Booysen at Sir Richard Branson's private Necker Island in the British Virgin Islands, according to US media reports. The 28-year-old, who has more than 500 million subscribers and is the world's biggest YouTuber, announced the news with a joint Instagram post declaring he had "found MrsBeast," alongside wedding photos. The marriage caps a relationship that became public with a Christmas Day 2024 proposal, and comes despite Donaldson's reputation for elaborate online stunts, having said he wanted a private, intimate wedding.

Wedding photos showed Booysen in a lace wedding dress with several outfit changes throughout the day, while Donaldson wore a white tuxedo. Booysen, from South Africa, runs her own YouTube channel with nearly 140,000 subscribers, streams on Twitch and is a published author. Donaldson has built his fortune through viral giveaway videos and the Prime Video series Beast Games, though his media company has faced legal challenges, including a sexual harassment lawsuit and disputes over contestant treatment in Beast Games.
