"So You Think You Can Dance" choreographer, Mia Michaels, has officially announced that she is leaving the reality series. No reason has been given at this time and people are starting to wonder as to why she quit so suddenly. There are dozens of rumors floating around that Michaels has cancer as photos (which we have yet to see) have been popping up showing the choreographer with a shaved head. For now, until we hear otherwise, we're going to assume the cancer ordeal is just a rumor. "It's been an amazing five years on SYTYCD. I thank them for all the great memories and movement I have been able to create for the world. Today was my official resignation of the U.S. show and look forward to what's ahead for me", said Michaels.
