Kane Brown and Katelyn Perform Duet On Stage For The First Time

Kane Brown and his wife, Katelyn, have been performing their duet "Thank God" at shows in Canada over the last week. The crowd response has been wonderful.

Kane and Katelyn shared a clip of the first song performance together on Instagram. Kane captioned the clip, "My baby's first time on stage singing our song together (heart emoji); she killed it, of course, and I'm so proud of you!!!! (Thank God)!!!!! Ottawa, Canada, y'all slayed."

Several fans responded to the post, including one who wrote, "Love this! Y'all's voices together… Y'all should sing 'Baby It's Cold Outside!' Your perfect blend would make it precious!!" Another fan gushed, "You rocked this girl! And the way your man is looking at you is everything." One more fan commented, "Love this song so much."

In another post, Katelyn wrote, along with images of the couple on stage and flowers in her arms, "Feeling so much love." One fan reacted to that post, "So much talent.. and love. Stay in this place…stay true."

In the third post to Instagram, Katelyn shared a video clip of getting ready for the performance and clips from the whole weekend. She wrote, "This past weekend in Canada has been a dream. Thank God has been such a special song, but I was so nervous for the day we actually performed it. Four nights in a row, and every night felt just as magical as the night before… and scary, lol. I feel so blessed to get to share these moments with the love of my life and be an example for our girls to have courage and overcome fears. Hearing you all sing back every word left me speechless every night. Thank you, @kanebrown, for believing in me, supporting me, and, most of all, loving me the way you do. Thank God for giving me you."

Kane Brown and his wife, Katelyn Brown, are celebrating their fourth wedding anniversary today (10/12), and the two are duet partners on their new single "Thank God," which has been moving up the country charts since it was first released a couple of weeks ago.

While neither Kane nor Katelyn has posted anything to their social media today in honor of their big day, Katelyn did share a post from Kane Brown Family, his fan club, which wished the couple a happy day. Katelyn also loved the posted with emoji hearts.
