MrBeast admitted he’s borrowing money from his mom to pay for his upcoming wedding to Thea Booysen — despite being worth an estimated $1 billion.

The YouTuber, whose real name is Jimmy Donaldson, responded via X after a fan post described him as “the only billionaire under 30 to not have inherited his wealth.”

“I personally have very little money because I reinvest everything (I think this year we’ll spend around a quarter of a billion on content),” he wrote.

“Ironically i’m actually borrowing $ from my mom to pay for my upcoming wedding lol,” Donaldson, 27, continued.

“But sure, on paper the businesses I own are worth a lot.”

The content creator — who has more than 400 million subscribers — rose to fame on YouTube by sharing over-the-top stunts and challenges.

He has also garnered popularity with his fan giveaways, offering up luxurious gifts like cars.

Donaldson expanded his fanbase when he released Season 1 of “Beast Games” on Prime Video in December 2024.

During the competition series, one out of 1,000 participants took home $10 million.

The show, which garnered 50 million views within 25 days of its release, has already been renewed for two more seasons, per Variety.

Donaldson also owns Feastables chocolate and snack brand, as well as the MrBeast Lab toy line.

As for his personal life, the entrepreneur began dating Booysen, 27, after they met in her home country of South Africa in 2022, according to People.

They took their romance public at the Kids’ Choice Awards in April of that year.

Donaldson popped the question on Christmas in 2024.

Days later, the couple told People they were thinking about having a small island ceremony.

“We’re not going to try and have a big, extravagant wedding,” Booysen said. “It’s going to be nice, but it’s certainly going to be intimate [with] close family and friends.”
