Iggy Azalea has criticised her fans for their lack of concern for her mental health when badgering the rapper over the release of her new EP.

The 29-year-old's hotly-anticipated EP, Wicked Lips, finally dropped on 1 December, more than two weeks after its scheduled release.

Disgruntled fans of the star had criticised her over the delay, which she explained as being due to missing the deadline on mixing a track, and claimed she "wasn't happy" with the new tunes.

Responding to a tweet making the claim on Friday, Iggy wrote: "No, I'm very happy with the EP. Very proud of every part of it. I just don't f**k with 'fans' who don't respect when people voice that they need a min to be mentally okay.

"Y'all fake care about mental health until you are slightly inconvenienced by it, and that's the tea."

The original tweet she was quoting in her response, read in Portuguese: "'Iggy Azalea says she is not happy with the release of the EP Wicked Lips and that fans have not respected her mental health."

Responding to the initial backlash over the delay, the Fancy hitmaker attempted to explain the situation, writing: "Please cut me some extra slack guys.

"I hear your frustration about the EP delay. I'm not ignoring your questions because I don't care. Sometimes I can't give fans explanations because I'm just not comfortable sharing everything publicly. I appreciate you guys understanding."

Wicked Lips and its lead single Lola, which features Alice Chater, have received generally positive reviews.
