Pitbull brought a record-breaking crowd to Hyde Park in London for the greatest party on earth. He set the record for the highest recorded attendance for the festival, at nearly 70,000 - and broke a Guinness World Record for the largest gathering of people wearing bald caps, at 22,141 🧑‍🦲 @danquinnell was there to capture it all. #pitbull #bsthydepark #hydepark #baldcap
