Evan Spiegel is another technology billionaire. You may not know his name, but you probably use his invention. He's the man who gave the world Snapchat, and has raked in over three and a half billion dollars from the app.
His wife, Miranda Kerr, didn't need him for his money. She was once one of Victoria's Secret's top models, and her good looks and sense of style have brought her a $45m fortune of her own. She briefly dated Orlando Bloom before settling down with Spiegel, whom she's known since childhood.
