The fabulous life of Italian denim god Renzo Rosso, the billionaire founder of Diesel

Diesel founder Renzo Rosso has built a clothing empire.

The "hard-partying, trash-talking billionaire bad boy" - as W Magazine called him - went from son of a northern Italian farmer to amassing a small fortune.

He first appeared on the Forbes billionaires list in 2012, and he currently has a net worth of roughly $3 billion, which he amassed through provocative advertising, savvy retail acumen, and smart business sense.

Though he's since relinquished the reigns of the company he created, the 60-year-old still serves as president of its holding company, OTB (which stands for Only The Brave, a company motto), and it doesn't seem like he'll slow down any time soon.

Rosso sat down with Business Insider to give us a small peek into what his fabulous life is really like.
