California's Long Beach Press-Telegram said the cause of the musician's death Tuesday was not immediately disclosed.
He had suffered strokes in 2007 and 2008, the newspaper noted.
Before establishing himself as a successful hip-hop artist, Hale served three years in the U.S. Marine Corps.
He later collaborated with rappers such as Snoop Dogg, Warren G, RBX and Daz Dillinger.
Snoop Dogg posted a Twitter tribute to Hale shortly after his death.
Calling Hale one of his best friends and a "true legend" in hip hop and R&B music, Snoop also added the message, "All doggs go to heaven," TMZ reported.
