Iggy Azalea has vowed to take better care of herself in 2015 after doctors diagnosed her with temporomandibular joint dysfunction (Tmj) last month (Dec14).

The Fancy rapper revealed her health news to fans during a New Year's Eve message on Twitter.com, informing them she was planning to ring in 2015 at Britney Spears' concert in Las Vegas before returning to work on her second album next week (beg05Jan14).

She wrote, "Also last month I was diagnosed with Tmj which isn't the best... I'm gonna make more of an effort to take care of myself in 2015, stay away from all the drama & hopefully not have any flair ups.

"I don't think western medicine all the way acknowledges what a huge toll mental stress takes on our bodies. But I do believe it is a factor... Anyhow I don't think it will ever prevent me from doing anything I want to but it has made me realize it's important to look after yourself."

The rapper's newly-diagnosed condition is related to jaw pain and stiffness.
