Madonna Louise Ciccone

The Material Girl's recently wrapped Rebel Heart tour grossed $170 million, contributing to Madonna's career total of an estimated $1.4 billion on the road. The latest cash infusion adds to a fortune already rich with royalties and real estate, including a town house on Manhattan's Upper East Side apparently purchased at the bottom of the market and an art collection reportedly featuring works by the likes of Picasso, Kahlo and Man Ray. Madonna, mother to Lourdes 26, Rocco 22, David 17, Mercy James, 16, and 10-year-old twins Estere and Stelle, is said to be planning to divide the rights to her songs equally among her six children. In 1992, Madonna launched her own multimedia entertainment company, Maverick, in partnership with Time Warner. This resulted in one of the most lucrative contracts ever offered to a pop star at the time, reported to be worth as much as $60 million over seven years. From a clothing range for H&M that reportedly earned her $4 million, to the Material Girl clothing line inspired by her iconic '80s style, Madonna also found success in this realm. She even ventured into skincare with her 2014 Japanese launch, MDNA Skin. Madonna’s real estate investments have been profitable, as she owns properties in London, Beverly Hills, New York City, Lisbon, and more. Her extensive art collection, rumored to be worth about $100 million, further adds to her wealth.
