Kirsty Bertarelli could probably have relied on her looks to make her a fortune even if she hadn't both been born and married well. Bertarelli is a former 'Miss UK' and followed that up with a second-place finish in the 'Miss World' pageant of the same year. She could command huge fees for modeling, and would likely have found her way to becoming a millionaire. Given that her family is the owners of the British ceramics firm Churchill China, she didn't have to worry about that.
Being one of the world's most beautiful women will naturally make you attractive to the world's richest men. That turned out to be the case when Bertarelli met her husband, Swiss business tycoon Ernesto Bertarelli. Taking on his surname saw her net worth jump to nearly $9bn, making her the richest woman in Britain. She spends her money on recording and releasing her own music, as well as a slew of charitable causes.
