The country superstar, 34, and the hockey player, 37, were hit with split rumors last week, but Fisher addressed the speculation on his Instagram account over the weekend.
“We’ve never been better. Thanks,” the athlete responded after a fan wrote that she was “praying for you and Carrie.”
Fisher’s post was a passage taken from the bible, reading: “Search me, God, and know my heart; test me and know my anxious thoughts. See if there is any offensive way in me, and lead me in the way everlasting.”
Though their relationship is going strong, Underwood and Fisher — who wed in 2010 — have indeed had a trying few months.

The American Idol alum has been keeping her fans posted on her progress, however, and Fisher has been by his wife’s side during her recovery.
“My boys make work outs fun (and a bit less productive, but that’s ok)!” she captioned the photos on Instagram.
