Twins and sisters must be common in billionaire families because here's another pair who are enjoying their father's wealth. Norwegians Katharina and Alexandra Andresen are barely half way through their twenties, but each of them has a net worth of $1.5bn. That comes from the investment company their father owns and operates, which is known as 'Ferd.' Managing numbers and spreadsheets aren't as exciting as being a movie star, but as we're seeing time and again it's a sure-fire way of bringing in big money.
The two sisters appear to have very different ideas of what they want out of life. Katharina looks to be preparing herself to take over control of Ferd one day - she's taken on an internship with corporate giants Ernst & Young. By contrast, Alexandra is far more interested in horses. She's a professional equestrian who has won awards in many facets of the sport, dressage in particular.
