Born in Abilene, Texas, in 1980, Simpson rose to fame as a pop singer and reality-TV star before building one of celebrity fashion's biggest success stories. Spanning 34 product categories, the collection grew from clothing into a sprawling lifestyle brand, reported to reach $1 billion in annual sales by 2014.
Beyond the label, Simpson has extended her name across fragrances, footwear and maternity wear, and judged designs on two seasons of the reality series Fashion Star.
