American hip-hop artist Pitbull achieved a Guinness World Record during his performance at London's BST Festival in Hyde Park on July 10, 2026, by assembling the largest gathering of people wearing bald caps. More than 22,000 of his fans—whom he calls "Bald Es"—participated in the event, coordinating to wear identical headwear for the occasion despite most having natural hair.

The record attempt originated from a social media initiative when podcaster Jack Remmington, a devoted fan, posted a TikTok video proposing the challenge to fellow supporters attending the festival. The achievement was officially confirmed through a structured verification process involving 400 volunteer counters working on the ground and 42 drones positioned overhead to capture comprehensive documentation for Guinness World Records' authentication.
