The 31-year-old singer and her 33-year-old hockey player husband spoke to Us Weekly at the Time 100 gala on Tuesday. Underwood was among those honored at the event.
"We actually went away a few months ago to Turks and Caicos for the Olympic break for a week or ten days," Fisher begins. "It was just awesome. It was nice to get away."
"[Carrie's] actually real busy doing a lot of writing and stuff," he continues. "I've been just kind of hanging out, just kind of being home and enjoying that."
Underwood has been busy working on her new album, and husband and wife agree that Fisher "stay[s] out of her way" when the singer is in work mode.
"That whole creative process is such a weird thing," Underwood says of her need for space. "I've talked to other people in the music business and friends and what they do and we all kind of have our own 'isms."
"I go in and I'm like caffeinated," she jokingly continues. "I get jacked up on caffeine and then I come home and crash."
The singer confirms that she has "been writing quite a bit" and says the process is "exciting." She reveals that the new album, her fifth studio release, "definitely has a different sound."
"There are some thematic things that are quite different," she says. "I love strong women. So I want things that I can get on stage and just feel empowered."
Underwood and Fisher enjoy alone time with a "glass of wine," and plan to spend time in Canada with Fisher's family this summer.
