Kelly Clarkson left The Voice because she was struggling a lot in her personal life, particularly dealing with the aftermath of her divorce, and she didn't want to "fake it" by putting on a smile when she didn't feel like smiling. She felt the need for a fresh start and moved from Los Angeles to New York, where she relocated her family and her talk show. Clarkson described this decision as difficult but necessary for her well-being, saying she couldn't keep pretending to be happy on the show and that the move lifted a heavy weight off her. She wanted to be genuine and truly happy in her work environment, which led to her stepping away from The Voice after several seasons as a coach.
