Remember a while back when Carrie Underwood posted that video of her husband Mike Fisher singing a Garth Brooks song? She captured it saying that maybe there would be a duet coming soon. However, Carrie immediately regretted that because Garth Brooks SAW the video and said he’d love to do a duet. The Problem? Dueting with Garth is something Carrie has ALWAYS wanted to do…but guess what? Her husband has officially done it first!
