Ireland, who has appeared on three Sports Illustrated covers, makes most of her money by licensing a slew of products, including furniture, windows, and mattresses to hair care, perfume, and shoes. Her clothing products include bridal dresses, furs, bras, and business suits.
As a comparison, Martha Stewart is also estimated to be worth $250 million also — but Ireland has sold $2BILLION worth of retail products. Stewart? Less then half that, at a measly $9 million.
