Reba McEntire has a lengthy career’s worth of wisdom to pass along that any younger country artist would love to soak up like a sponge. Kelsea Ballerini was the beneficiary of some of that recently when she took over for the departing country legend as a team leader on “The Voice.” During the season premiere on Monday, Kelsea found a sweet letter from McEntire on her chair. “Dear Kelsea, I heard you would be the new coach this season and I’m just so excited for you. It’s up to you to keep country alive on the show and I know you’ll do a terrific job. Now go out there and show those boys who’s the boss.” She added that she’d left Ballerini a “little good luck charm in case you need it.” When the newest coach turned around in her chair, she saw that Reba had left her the crown she was given when she was dubbed “Queen Reba” on the show. Kelsea placed it on her head, saying, “I feel so fancy!”
