Hilary Duff's latest Instagram post is what dreams are made of. Duff, 38, sent fans into a frenzy on Tuesday, October 7, when she shared photos and a video of herself in what looked to be some sort of rehearsal studio. In one snap, she took a mirror selfie as she knelt on the ground in shorts and a tank top, flashing a huge smile. A mic stand could be seen in the background. The second photo showed Duff in a different outfit - this time wearing animal print pants and a crop top - as she covered her face with her hands and stood in front of the mic.
