Zoomer legend Madonna is celebrating her 60th birthday today.

The Queen of Pop has been a superstar for at least half of her life, topping the charts since 1984 with 12 number-one hits and eight number-one albums.

Over the years she’s gone from a dance-pop provocateur to a humanitarian who’s worked to help children in Africa. She has also spoken out on topics like gay marriage, women’s rights, and education for girls worldwide.

She is the richest female artist in the U.S. with a net worth of $580-million. That puts her comfortably ahead of Canadian chanteuse Celine Dion by about $200-million.
