'The Voice' season 24 premiere marked the show’s first-ever without Blake Shelton, but wife Gwen Stefani made sure he was remembered. Gwen returned to the singing competition following Blake's departure after season 23 earlier this year. To honor him, she donned 'Shelton' and 'Stefani' necklaces for the big night, keeping her hubby of two years close to her heart as she heard the first Blind Auditions. 'The Voice' airs Mondays and Tuesdays on NBC. Source
