The record was originally due out on November 15, but the 29-year-old pushed it back a week after failing to mix the vocals on one of the songs in time.
However, while the star promised it would drop a week later, on November 22, fans took to Twitter to fume as the Fancy hitmaker failed to respond to messages about the whereabout of the project.
"Watch her delaying the EP again ... which is very uncool to delay it 2 times in a row," one fan fumed. "But why are we surprised? We always had to fight with that... The New Classic, Digital Distortion... shouldn't we be so used to it?"
Another wrote, "What happened to Wicked Lips? Isn’t it supposed to be released already?"
It wasn't all bad for Iggy though, as some fans pointed out, that since leaving former label Island Records last year she's an independent artist, meaning she funds and navigates all aspects of her career.
"She's independent," wrote one user. "Everything she does she funds so obviously it's gonna take longer."
The delay comes after it was reported the "Kream" star's home with beau Playboi Carti was robbed of over $350,000 in jewellery last week - with high-end watches, chains, rings and bracelets, and a $35,000 diamond engagement ring among the list of items taken.
