A spokeswoman for Harris’ company, One Talent Management, said Harris had died of natural causes and that funeral arrangements were pending.
She worked at the William Morris Agency before joining United Talent Agency as a partner shortly after its formation in 1991. Harris remained at UTA until 2003, when she formed a management company with Heather Reynolds.
Harris was the CEO of One Talent Entertainment. She and Theron parted ways amicably last year; Harris had repped her dating back to the middle 1990s at UTA.
