A Nigerian woman,Folorunsho Alakija edges out Oprah Winfrey to become the richest black woman in the world.

A report by African Business Magazine reported that a Nigerian woman,Folorunsho Alakija has beaten edged out Oprah Winfrey to become the richest black woman in the world. Folorunsho Alakija, a 61-year-old woman from Nigeria who is reportedly worth at least $3.2 billion, or roughly $500 million more than Oprah's $2.7 billion net worth, Ventures Africa reported. Alakija is the founder and owner of Famfa Oil, which owns a 60 per cent interest in OML 127, an offshore oil field that produces roughly 200,000 barrels of oil per day and is worth an estimated $6.44 billion. Folorunsho Alakija, a 61-year-old oil tycoon from Nigeria, is reportedly worth at least $3.3 billion, or $500 million more than Oprah's $2.7 billion net worth. Also a fashion designer and philanthropist, Alakija is married and has four grown sons, as well as one grandchild. She owns at least $100 million in real estate and $46 million private jet, Ventures Africa reported. Born into a wealthy Nigerian family, Alakija started out as a secretary in the mid 1970s at the now defunct International Merchant Bank of Nigeria. Several years later, she quit her job and moved to London, where she studied fashion design. She later returned to Nigeria and launched her fashion line, Supreme Stitches, which caters to upscale, high-society women. While she was building her name as a fashion designer, Alakija in 1993 applied for an Oil Prospecting License -- an expensive permit that allows for oil exploration in a specified area. The Nigerian government granted her request and allocated a 617,000-acre block of land to Alakija for oil exploration -- but she knew nothing about finding and extracting oil. Alakija's sons now run Famfa Oil and her husband, Modupe Alakija, is the chairman of the company. She recently purchased a $102 million property at One Hyde Park in London, as well as a Bombardier Global Express 6000 jet, which she bought earlier this year for $46 million. Her charity, Rose of Sharon Foundation, gives out small grants to widows and orphans.
