The Voice: Why Reba McEntire and Nick Jonas' Reunion Is 'a Full-Circle Thing' (Exclusive)

Reba McEntire brings on former coach Nick Jonas as her Battle Round advisor on 'The Voice,' which airs on Mondays and Tuesdays at 8 p.m. ET/PT on NBC. The pair first met on Broadway more than 20 years ago, when they starred together in 'Annie Get Your Gun,' making this project a full-circle moment. Reba tells ET's Cassie Dilaura, 'Nick was the best choice... he's so knowledgeable and gives great advice,' while Nick jokes he's only there 'because Joe was unavailable.'
