Hymns was the couple's seventh and final album, released on Feb. 12, 2016. Less than one month later, on March 4, Joey died following a lengthy battle with cancer.
"It finally came out a year ago and we sat together in the final days and watched this awards ceremony last year," he shared. "She said, 'If we get nominated, promise me you will come.' I said, 'I will.' And, she said with a smile, 'Remember, if we win, I'll know before you know.'"
During an interview with ET's Sophie Schillaci on Sunday, Feek said he tried to share the good new with his daughter, Indiana.
"I just actually tried to FaceTime her," he said. "But, she [might be] playing outside with her grandma. Joey's mother is with her, and also my daughters. And, she's just precious."
"She turns three next week, actually this Friday," he continued. "So, it's a big week for us. Joey's family is coming down to our farm in Tennessee, and we're gonna have a birthday party."
Joey was diagnosed with cervical cancer in 2014, just months after giving birth to Indiana. In October 2015, Joey shared the news that her cancer was terminal, and that she had decided to stop treatment. She was 40 years old at the time of her death.
