"At the end of the day... it's no different than if Gwen and I were playing cards," Shelton recently told ET. "She wants to win and I want to win, and that's what they pay us to do on this show, is to try to win."
However, Shelton says it's "harder" for Gwen when it comes to duking it out during production.
"She's not competitive. She'll be the first to tell you," Shelton said, adding, "Right up until it gets competitive and then all of a sudden she [really] is."
For Shelton, however, getting to work alongside his girlfriend -- even when she manages to steal some of the talent he had his eye on during auditions -- is a better experience than bickering with his longtime frenemy, Adam Levine, who stepped away from the show after last season for the first time since the show started.
"I'll take this way over whatever I had with Adam," Shelton said. "I want him to know that he can still kiss my ass wherever he is right now."
