Hill and husband McGraw, both 49, will work with coaches Adam Levine, Blake Shelton, Miley Cyrus and Alicia Keys as they mentor their respective teams. In particular, they will give the aspiring singers tips before they duke it out in the knockout rounds.
"I think having the perspective of performing live in many different venues, from clubs to stadiums, will help us in working with the Voice artists this season," Hill said in a press release statement. "It’s important that they be able to connect with their audience."
McGraw added: "I really like to dig into songs and how they need to be presented in a live environment. I’m looking forward to working with the coaches to help the artists reach their potential."
The couple — married since 1996 — will head to the L.A. set later this month to film. Former Voice key advisors include Taylor Swift, Rihanna and Coldplay's Chris Martin.
Hill and McGraw are hitting the road too. On Tuesday, during a surprise performance in Nashville, they announced a 65-city tour. The Soul2Soul world tour will kick off in New Orleans April 7. They previously toured together in 1996, 2000, 2006 and 2007.
"OK, so we are going back on the road, on tour," Hill said at the Ryman Auditorium, via the Today show. "We are going to go from side to side, south to north, all the way around the globe."
