Hayden Dubose is an unseen character featured in Grand Theft Auto V.
He seems to be rich and successful, and is married to his third wife. He has two children from previous marriages, a daughter, Melinda and an unnamed son, both of whom are attending boarding school. His current wife, Kimberly and both ex-wives were clients of tennis coach Kyle Chavis.
He is a friend of Michael on Lifeinvader. From what can be seen on his Lifeinvader page, he's apparently racist and addicted to sex. His daughter Melinda is embarrassed by his Lifeinvader posts.
