James, former star of "Monster Garage" and "The Celebrity Apprentice," infamously was caught cheating on his third wife, actress Sandra Bullock, days after she won an Oscar for her performance in "The Blind Side" in 2010.
People.com said James' 9-year-old daughter, Sunny, and DeJoria's 10-year-old daughter, Bella, acted as flower girls at the wedding Sunday.
DeJoria and James got engaged late last year.
