Busy with her new album, tour, special appearances, charity work, even acting, Underwood said the couple has no plans yet to start a family.
"We just want to be together and keep it as simple as possible. And I think a baby would just make things so complicated right now," she said.
When the tour wraps up in December, the star plans to settle down in Canada with her new husband.
"I'll be more home-based. So I'll get to spend, you know, my days with him," she said. "We'll be more like a normal couple."
