Adam Levine has been given a warning ahead of his return as a coach on The Voice US, according to reports.

The Marron 5 frontman, 45, was one of the original spinning red chair occupants when the show first launched back in 2011.

During his time he managed to get a hat-trick of wins under his belt, including Javier Colon, Tessanne Chin, and Jordan Smith, before leaving in 2019 following 16 series.

He is set to take his place alongside John Legend, Michael Bublé and Kelsea Ballerini when the show returns next year for season 27, but it has been claimed not everyone is happy about the prospect.According to the Daily Mail, some staff members remember him as “cocky” during his first run, and are worried it will be the same this time around.

“Not everyone is happy with Adam coming back to the show,” a source told the publication.

“There have been many changes behind-the-scenes, but there are a lot of people still there from Adam’s time before and don’t like that he will be returning, because, towards the end of his last run, he was cocky, arrogant and seemed entitled.

“People get second chances, and maybe Adam will change. But if he remains the abrasive Adam from the past, then they will get rid of him again.”

The She Will Be Loved hitmaker is the show’s second longest serving coach behind country singer Blake Shelton.

Announcing his return to The Voice US earlier this month, Levine penned on social media: “The OG is back in the building! I’M COMING BACK to #TheVoice next Spring 2025. Can’t wait!”

Fans are excited – the post has wracked up nearly 100,000 likes.

The Standard has contacted a representative for Adam Levine for comment.
