TMJ (short for temporomandibular joint dysfunction) is the medical term for jaw pain or dysfunction. While TMJ's seriousness depends on how severe the pain is, it's definitely a big deal for someone who raps for a living.

In addition to the medical revelation -- and blaming mental stress for her health issues -- Azalea also revealed that she's starting work on her second album next week and hitting Las Vegas for Britney Spears' New Year's Eve show Wednesday night (Dec. 31).
