As if Bono needed anything else to sing about. The singer could become a billionaire when Facebook goes public Friday.
Chances are U2 front man Bono doesn't need any cash but that doesn't mean Friday won't be a beautiful day for the singer.
When Facebook begins selling shares of its social network to the public, Bono will become the richest rocker in the world.
The Irish singer owns about 2.3 percent of the company through his investment group Elevation Partners.
Bono's firm bought $90 million worth of Facebook shares in 2009 on the secondary market. His shares could now be worth more than $1.5 billion.
If the estimates are accurate, Bono would surpass Beatles great Paul McCartney who is believed to be worth about $1.05 billion.
