Madonna, 65, concluded her Celebration Tour with a record-breaking performance on Copacabana Beach in Rio de Janeiro, drawing an audience of 1.6 million people, making it the largest-ever concert for a female artist. Dressed all in black, she transformed the beach into a massive dance floor, where she performed hits like 'Hung Up On Tokisha' and 'Nothing Really Matters.' The free event not only marked the end of her world tour but also featured a surprise appearance by Anitta, further electrifying the crowd.
