After eight years and 16 seasons on The Voice, one of the original coaches, Adam Levine, is bidding farewell to his big red chair. 

"After the first day of shooting, I sat there, stunned," the Maroon 5 frontman wrote in a lengthy social media post on Friday (May 24), thanking everyone on the singing competition for the opportunity to be a part of the show. "I said to myself 'theres some magic here. Something is definitely happening.' It went on to be a life shaping experience that will be close to my heart forever."

Gwen Stefani will replace Levine in the fall. The announcement comes just a few weeks after he retweeted a promo in which he was announced to be returning for another season.

Fellow coaches John Legend, Kelly Clarkson and Blake Shelton were equally as upset about the news as The Voice fans. They took to social media to share their thoughts, including Shelton admitting that he's "gonna miss working with that idiot."
