“Yesterday, I took a hard fall while rehearsing for #VillainsNight,” Burke tweeted today of the accident Sunday. “It’s one of those things that can happen in a split second.” In a second tweet, Burke seemed to confirm she'll be performing tonight with partner A.J. McLean. “Thankfully, I have the best partner I could ask for that was there to pick me up off the ground. Keeping our fingers crossed for only planned mishaps during the show tonight!!” she tweeted.
