It's doubtful that Rob Dyrdek (born June 28, 1974 in Kettering, Ohio) is gay since he is known to date women.
The last person we found the professional skateboarder, actor, writer, and producer had been dating was actress Erika Schaefer (born Erika Ashley Schaefer on March 10, 1984 in Nashua, New Hampshire).
5' 6" Schaefer attended ASU, but didn't graduate, instead deciding to pursue her acting career.
5' 7" Dyrdek dropped out of high school before his senior year to pursue his professional skating career.
Rob started his TV career through the MTV series Rob & Big which ran from November 2006 to April of 2008. He began Fantasy Factory in 2009, and by its third season he became the highest paid reality TV star of the time, earning $140,000 per episode, according to Forbes magazine.
