Rob Dyrdek was born in Kettering, Ohio to Gene and Patty Dyrdek. Dyrdek was involved in sports as a child and began skateboarding at the age of 11 when he received his first skateboard from professional skater Neil Blender Of his early interest in the sport, Dyrdek said, "I was a pretty driven young man. I was so focused on becoming a pro skateboarder. I would sit in school and think about all the tricks I was going to do, then I’d get out of school and skate until they made me come inside." At the age of 12, Rob acquired sponsorship from the same company Blender rode for and began his skateboarding career. A few years later, Dyrdek and Blender quit their board sponsor and created Alien Workshop – Rob’s current board company.

In 1995, after several years of being outed as lesbian by the tabloid press, he publicly self-identified as such in a cover story in a leading American gay monthly magazine, The Advocate. Bono went on to discuss the process of coming out to oneself and to others in two books. Family Outing: A Guide to the Coming Out Process for Gays, Lesbians, and Their Families (1998) includes his coming out account. The memoir, The End of Innocence (2003) discusses his outing, music career, and partner Joan's death from non-Hodgkin's lymphoma.

Between 2008 and 2010, he underwent female-to-male gender transition. A two-part Entertainment Tonight feature in June 2009 explained that his transition had started a year before. In May 2010, he legally changed his gender and name. A documentary on Bono's experience, Becoming Chaz, was screened at the 2011 Sundance Film Festival and later made its television debut on OWN: Oprah Winfrey Network.
