'The Voice': Why Blake Shelton Wants Lowkey Celebration With Gwen Stefani After Season 23 Finale

Blake Shelton chats with ET's Cassie DiLaura ahead of the season 23 finale of 'The Voice.' The country star celebrates his final season as a coach on the singing competition series following 23 seasons, 12 years and nine wins. As Blake tells it, don't expect wife Gwen Stefani to throw him anymore parties after his Walk of Fame ceremony last week. He also has two artists competing in the finale, NOIVAS and Grace West, and he suspects 'either one of them could win.' 'The Voice's two-part finale airs Monday on NBC.
