Trisha Yearwood and her husband, Garth Brooks, have both had successful solo music careers, but now the songstress hints they may join forces and work on a new project and tour together.

“It’ll be a whole different ball game, you know, as man and wife to go do this together. So I’m looking forward to it,” Yearwood tells CBS News. While the 48-year-old refused to disclose many details about the upcoming collaboration, her husband has said he would love to hit the stage with her after his three daughters have all graduated from high school.

“I’d love to tour again with Miss Yearwood and have no guilt,” Brooks noted last year. “But I’m still two years away.”

One thing we do know Yearwood is working on is a collaboration with Kelly Clarkson and Reba McEntire.  "We've become friends, and I love both of them," Yearwood gushes. "We've been toying with the idea of working together. Kelly's working on a little something that we sang on ... one song, at this point. Right now."

The newly-svelte singer, who showed off her 35-lb. weight loss during the ACM Awards earlier this year, is also the star of her own cooking show, 'Trisha's Southern Kitchen' on the Food Network. But while the Georgia native admits she loves cooking -- including her new lighter and healthier fare -- she insists music is still her first love.

"If you said, 'Trisha, you have to pick one thing that you can do every day for the rest of your life, I would pick music," Yearwood maintains. "Absolutely. That is what feeds my soul."
