After Blake Shelton retired from the show, there was an obvious vacancy to fill. While the judges often rotate from season to season, Blake had been in 23 seasons. The replacement would surely need to be someone of equal star power.

So, NBC managed to convince none other than Reba McEntire to fill the gap. Another country star, she definitely has the celebrity status to draw attention.

Reba is a double threat, finding success in both music and acting. The icon has had over 100 singles hit the Billboard Hot Country charts and sold more than 75 million records. She's a seasoned veteran in the music industry, decorated with plenty of awards including seven recognitions for Academy of Country Music's Top Female Vocalist Awards.

Kelly Clarkson also stepped away from the show this season. So, John Legend stepped in to take her place. He's not quite as "new" as Reba is, though. In the past, he served as a coach for six seasons. Plus, he even won Season 16. Having John back is certainly some steep competition for the other judges on the roster.

John is a singer-songwriter who built his career behind-the-scenes, supporting other musicians, until catapulting into the definite spotlight in 2013 with his song "All of Me." Before becoming a shining star, he was still well respected by his peers with his music featuring production credits from Kanye West and will.i.am on just his debut album.

Finally, Chance the Rapper departed from the show, too, this season. Gwen Stefani was tapped to join the crew. Maybe she was the true replacement for her husband, Blake? Gwen is no stranger to the show, being a part of the team seven times previously.

She is pop music royalty, for sure. Gwen started her career in the music group No Doubt before splitting off on her own solo journey. In the early 2000s, she became a household name and solidified her role in music history.
