On the 30-second promo for the episode, the former talk show host asks Levine for his take on marriage, and questions Shelton on how he makes his marriage with Miranda Lambert work, among other things.
Host Carson Daly and social media correspondent Christina Milian also popped in for the sit down, which as usual, is being kept under tight wraps.
