Madonna (1958) is an world famous pop singer.
Portrayal on Spitting Image
In some sketches she was shown having a singing belly button. In almost every appearance she changed her hairstyle and clothing. One memorable sketch shows her desperately trying to be noticed by a crowd of people, but nobody recognizes her. Eventually she shows her breasts, whereupon everybody recognizes her again.
Her failed marriage with Sean Penn was spoofed as well during the 1980s.
