Fans of rapper Pitbull have established the first-ever Guinness World Record for the largest gathering of people wearing bald caps, drawing 22,141 participants at a BST Hyde Park concert in London on Thursday. Guinness World Records confirmed the figure, noting no previous record existed for the category.
The attempt was monitored by 400 volunteers and 42 counters using drone footage to verify the headcount. Pitbull himself was required to don a bald cap to be included in the official tally.
The idea originated in 2025 when fan Jack Remmington posted a video on TikTok, which he later developed into a campaign with BBC Radio 1 presenter Greg James. James presented the record attempt at the show.
