Who drew a record-breaking crowd of 2.5 million at a 2025 concert in Rio?

On May 3, 2025, Lady Gaga performed a free concert on Copacabana Beach in Rio de Janeiro, drawing a crowd of over 2.5 million people — the largest audience of her entire career.
The show was part of her global "Mayhem" promotional tour for her new album and set a record for the biggest crowd ever gathered by a female artist.
The event was held under tight security after Brazilian authorities reported stopping a potential terror threat ahead of the concert.
According to Rolling Stone and BBC News, the show featured a 90-minute set, drones, a floating stage, and a tribute to Brazilian fans: “This country gave me my voice.”
