"You're in love with Blake Shelton," Chelsea Handler joked to Adam. "You're not scared to admit that. You guys have been dating for what, two and a half years now? That's beautiful."
"We're having some sexual problems, though," Levine quipped, adding that Blake has issues getting it up. "He drinks a lot so...it's a problem. But it's fine. He's okay. We'll be all right. We'll figure it out somehow. That's why we get along, Miranda [Lambert] and I, so well, because we have so much to talk about," he added.
Relationship issues aside, Adam said when it comes to his coach duties on the Voice, he's clearly the best on the show. "I think I'm way better than Blake. That goes without saying," he joked, before adding, "All jokes aside, he is a really good coach. We all are good coaches."
