Amancio Ortega, #5 on the Forbes list, is worth $37.5 billion
This Spanish beauty is the daughter of Amancio Ortega, the founder of the global fashion firm Inditex, who Forbes says is the fifth richest man in the world.
Rumors have it that Marta, 28, is being groomed by her father to one day take over the international fashion company that owns the Zara retail chain.
However, Marta has been given no easy path and started at the bottom where she stocked shelves and dealt with customers. This may be hard work, but considering her father is worth $37.5 billion, it's probably worth it.
Marta is also an avid equestrian and recently married Spanish equestrian star Sergio Alvarez Moya.
