Some viewers of Dick Clark's New Year's Rockin' Eve may have **ticed that Iggy Azalea was acting somewhat peculiarly as she performed "Fancy" with Charlie XCX: She was dressed rather conservatively. This had **thing to do with a more interesting tweet she sent out early in the day where she confirmed that she had been diag**sed with temporomandibular joint dysfunction, or TMJ (she also an**unced she's working on a new album but we'll get to the good news later).
