"(It) makes me happy," the country singer said of his onscreen tension with the Maroon 5 frontman. "I live to make him feel bad about himself."
When asked about their "special relationship," the 37-year-old country singer joked, "I would say where there's smoke, there's fire. We're very attracted to each other. I'm already married, so it's never going to work out."
As for his three-time winning streak -- which might seem repetitive to some -- Shelton said he's happy to keep on winning.
"It may be [boring] to you, but it's very exciting to me," he said. "I don't care if they like it or not."
"Is it true that it's now named 'The Blake Shelton Show'?" Christina Aguilera joked on this week's episode.
But his fellow judges are doing their best to push him off his pedestal.
"I had a hard time getting people to come with me this year on my team," Shelton said of this year's selection process. "And Adam had some good points. He threw out some stuff about the NBA and how nobody's ever won four of anything in a row -- I can't remember what these stats were -- but he actually got in some people's heads and stole some people."
