Bono is known as for his philanthropy, stylish sunglasses and fronting iconic Irish rock band U2. But perhaps the co-founder of private equity firm Elevation Partners should be known better for his financial savvy.
Elevation Partners' 2.3 percent stake in Facebook, which it bought in 2009, has grossed Bono more than his whole music career, according to a report on U.K. news website the Mirror, citing The Sun newspaper.
The Mirror, which is the online edition of The Daily Mirror, a British newspaper, said that share is worth about $1.4 billion, making Bono the world's richest pop star. Still, other publications pointed out Bono's hefty portfolio, which also includes Yelp, doesn't exactly qualify him as a billionaire, since he must split his stake among the Elevation Partners team.
