After “Thank God” Success In September, Kane Brown and his wife Katlyn, released their first duet, Thank God. They have not performed the song together yet but they can't believe how fast the song took off. Kane shared that he thinks the song works because, it's a true love story. It's not two artists who are singing to each other and have no future with each other. I feel like people can relate to that. Plus, it's a beautiful song. Kane said he and his wife definitely do another song together. What is your favorite duet of all-time? Name a duet that was so good you really believed the pair was a couple?
