Pretty easy right? It's former Beatle Paul McCartney, right?
Well, that may be true, until the stock market closes today. As you may well know Facebook becomes a publicly traded company today and the money that's going to generate makes my head spin.
Paul McCartney's fortune is estimated to be just over $1 billion. Thanks to his 2.3% ownership in the social network, Bono from U2
is expected to bank around $1.5 billion by the time Wall Street rings it's closing bell.
