If you want to be a millionaire, think like a millionaire! Paul McCartney's fortune exceeded one billion dollars. He became the third musician in history to overcome the symbolic milestone. The richest is Jay-Z with 2.8 billion, followed by Taylor Swift with two billion dollars. The legendary 84-year-old former Beatle, according to Forbes, has a fortune of 1.4 billion. So much for "can't buy me love". Be kind!
