That same night, Miranda debuted “Trailblazer” with Reba McEntire and Lainey Wilson, just another expression of the bond between the women of country music. “I feel like I’m like big sister [to Ella],” Miranda says, “and we[‘ve] got Lainey, middle sister, and we[‘ve] got Reba, older sister, and it just feels like a good sisterhood to be in.”Miranda, Lainey and Ella will all vie for the female vocalist trophy at November’s CMA Awards.
