As Joey Feek continues her cancer battle, Rory Feek reveals something about the future. The 49-year-old sat down exclusively with Entertainment Tonight as he reveals that he won’t be continuing with singing and writing songs without his wife.

"This is the last record that Joey and I will ever get to make and the last songs we'll ever get to sing together," he says of their new album, Hymns That Are Important To Us, out Feb. 12 exclusively at Cracker Barrel. "I have no desire to go on singing or performing without her."

Moreover, he continues to reveal that the couple’s daughter, Indiana will be celebrating her second birthday on February.

"Her mama rocked her to sleep singing them and has even taught Indy how to sing along with sign language on 'Jesus Loves Me,'" he says. "Joey singing these songs is a big part of Indy's life so far, and I know that these songs will go on to be very important to her as she grows up and is able to hear Joey still singing them to her when we play the album."

Rory also dished out that Joey did laid down courageously most of her final vocal in a Georgia hotel room while undergoing chemo and radiation last year, as they recorder the album tracks at a studio in Nashville.

Meanwhile, Rory has been updating fans of her wife’s health on his blog, This Life I Live. The Joey + Rory singer recently confessed that his wife's condition had continued to "decline" and wrote, "I'd like to tell you that she's doing great and is going to beat this thing. But I can't."

"We've received hundreds, if not thousands of letters and cards and gifts that people have sent to us through all of this," Rory tells ET. "Many of them tell stories of their struggles with cancer, their families, and their faith. They write and share their hearts with us to encourage us, just as we strive to encourage them through our journey and my blog."
