World’s biggest YouTuber MrBeast marries longtime partner Thea Booysen

American YouTube sensation Jimmy Donaldson, popularly known as MrBeast,  has tied the knot with his fiancée,  author Thea Booysen.

The 28-year-old, who is the world’s most-subscribed YouTuber with over 500 million subscribers, announced the wedding on Instagram, where he shared a collection of photographs capturing different moments from the celebration.

The pair married on  British billionaire  Richard Branson’s private Necker Island in the British Virgin Islands, according to US outlets.

Booysen stunned in a floor-length lace wedding dress with a floral pattern for her big day, while Donaldson opted for a white tuxedo.

MrBeast described it as “the best day of my life” in the post.

Around 70 family members and close friends attended the week-long celebration, which reportedly began on July 14. Before the couple exchanged vows, guests enjoyed activities including snorkelling and kitesurfing. The private ceremony was officiated by a family friend who is an ordained minister.

Donaldson and Booysen’s relationship began after they met during a trip to South Africa in 2022. Booysen had been invited by a mutual friend to join the YouTube star for dinner, and the pair later started dating.

Donaldson popped the question to Booysen on Christmas Day 2024 while they wore matching MrBeast-branded festive jumpers.
