Azealia Banks has slammed Miley Cyrus and Nicki Minaj for making "basic ass" music.

The rapper is always vocal on Twitter and the latest subject she's jumped on is the feud between Miley and Nicki, which kicked off when the former Hannah Montana star seemed to suggest the Super Bass singer was rude during an interview.

It all came to a head at the MTV VMAs on Sunday, where Nicki called Miley out in front of the audience, branding her a "b***h".

Azealia thinks the whole thing is laughable, as in her opinion, neither artist makes worthwhile music.

"Miley Cyrus HAS to know her sh*t is whack as f**k. It has to be a joke... Isn't she making fun of herself? Yes? No?" Azealia queried on Twitter.

"It's so funny to wake up and see nicki and Miley or nicki and taylor fighting when you ALL make basic ass music. it's a ki !!!

"All of y'all b***hes are whack and make boring music and rip all ur styles off the downtown NYC girls (sic)."

Nicki seems to be the name on everyone's lips at the moment, as she also had some bad blood with Taylor Swift. When the rapper expressed her anger at her Anaconda video not being nominated for a VMA, Taylor mistook the comment for a dig at her.

Luckily the two pop babes have since made up and are back on great terms. They even opened the VMA show together, with Nicki posting on Instagram after: "Love the conversations I have with this girl behind the scenes. So glad we got to perform together. #Taylor (sic)"
