During the Academy of Country Music Awards, Shelton said he is open to marrying Stefani, whom he has been dating since 2015, reports aceshowbiz.com.
"I think about it but I don't think it's anytime soon or anything. The more time that goes by, I guess, the closer you would be getting to that," he said.
During the awards show, Shelton, 41, took the stage to perform while Stefani looked on from the crowd.
Shelton and Stefani became romantically involved while appearing as judges on the reality competition show "The Voice" shortly after splitting from their respective partners Miranda Lambert and Gavin Rossdale.
