"God bless Mr. [Kevin] Costner, he was like, 'No – you're going to dye it,'" Annable recalled to PEOPLE Dave Annable is embracing his natural salt and pepper look! In an exclusive conversation with PEOPLE at the season 2 premiere of Lioness on Oct.

Dave Annable revealed that Kevin Costner required him to dye his gray hair while starring on "Yellowstone." Annable portrayed Lee Dutton, John Dutton's ill-fated son.

On some level, both shows are familial dramas that center on a King Lear-esque patriarch whose children vie for control of their inheritance -- the Yellowstone Dutton Ranch, in the case of Taylor Sheridan's mega-popular neo-Western drama-- while also warding off the vultures circling from the outside.

Kevin Costner was so scared of looking old in ‘Yellowstone’ he got the actor who played his son on the show to dye the grey out of his hair.
