Country music's royal couple Faith Hill and Tim McGraw are joining Season 11 of The Voice.

NBC announced Tuesday night that for the first time ever, the singers that make it to the show's all-important knockout rounds will have the benefit of two powerhouse key advisors. The knockout rounds are the last obstacle the singers have to topple before they make it to The Voice live shows, where America takes over deciding who stays and who goes. Hill and McGraw will advise and offer their critiques to each singer from each team before their performances.

Together, Hill and McGraw are two of the most celebrated musicians in the industry. Hill has won five Grammy Awards and sold 30 million albums worldwide. McGraw recently became the first person to have three songs concurrently charting on the Billboard Country Music Airplay chart. They will bring their separate expertise to help the singers give their best performances.

"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," said Hill in a statement. "It's important that they be able to connect with their audience."

"I really like to dig into songs and how they need to be presented in a live environment," added McGraw. "I'm looking forward to working with the coaches to help the artists reach their potential."

The first key advisor for all teams was Coldplay's Chris Martin back in Season 6. Since then Taylor Swift, Reba McEntire, Fun singer Nate Reuss, Dolly Parton, Rihanna, Pink and current judge Miley Cyrus have all held the mantle. The knockout rounds pit each singer against another member of their team to become one of their coach's final four to make it to the live shows.
