Madonna is one of the most famous women in the world, and she is a role model for many younger pop stars, such as Britney Spears and Christina Aguilera. She released her first single twenty-five years ago, in 1982. Since then, she has recorded dozens of hits, released groundbreaking music videos, and starred in movies such as Evita and A League of Their Own. She is also a fashion icon. Whenever a new trend breaks, Madonna is one of the first people to make it her own.
