The material mom crosses the half-century mark this Saturday. If that doesn't make you feel old, check out our photo gallery of Madge through the years--there's a reason she's still getting our attention.
When she burst onto the scene in 1983 with her self-titled debut album, she may have been the only one who knew she was here to stay. This year, she surpassed Elvis as having the most top 10 hits in the history of the Billboard 100. She is the world's most successful female recording artist of all time and the top-earning female singer in the world, with an estimated net worth of over $400 million. Now 50 doesn't seem so old!
