Dancing With the Stars isn’t a competition for the faint of heart — as dance pro Emma Slater can attest to! Posting a video via her Instagram on Thursday, September 17, Slater, 37, revealed she had suffered a gruelling injury during rehearsal for the show. Slater warned in text overlaid on the video: “Don’t watch if you squirm easy!” She then showed her followers her detached toenail. “There’s a lot of people that want to do Dancing With the Stars, and they want to experience it, but there’s something you should know,” Slater said in the clip. “If you do Dancing With the Stars, this could happen.” Related: Emma Slater Taken to Hospital…
