Iggy Azalea has slammed "poisonous" and "miserable" Azealia Banks.
The two singers are currently locked in a bitter feud which started when Azealia slammed Iggy for not commenting on the shooting of black teenager Michael Brown or the death of African American Eric Garner after a police officer put him in a chokehold.
Yesterday Azealia kicked things off again when she claimed Iggy didn't deserve any Grammy recognition.
"Special msg for banks: There are many black artists succeeding in all genres. The reason you haven't is because of your p**s poor attitude," Iggy vented on Twitter.
"Your inability to be responsible for your own mistakes, bullying others, the inability to be humble or have self control. It's YOU!
"you created your own unfortunate situation by being a bigot and don't have the mental capacity to realize yet. Probably never will. (sic)"
Iggy is nominated for four Grammy Awards, with the ceremony taking place on February 8 at the Staples Center in Los Angeles.
In a radio interview with Hot 97 Azealia vehemently disagreed with the decision.
"When they give these Grammys out, all it says to white kids is, ‘You’re great. You’re amazing. You can do whatever you put your mind to.’ And it says to black kids, ‘You don’t have sh*t. You don’t own sh*t, not even the sh*t you created yourself.’ And it makes me upset," she fumed.
"Put [Iggy] in the pop category. Put her and Miley Cyrus in the same f**king box together. Don’t put her in hip-hop. Just because she’s singing, does not mean she’s rap music."
Iggy didn't take kindly to the comments and added more to her Twitter tirade.
"Now! rant, Make it racial! make it political! Make it whatever but I guarantee it won't make you likable & THATS why ur crying on the radio.
"Enjoy continuing to bang your head against that metaphoric brick wall & Savor this attention. I'm the only way you get ANY.
"You're poisonous and I feel genuinely sorry for you because it's obvious at this point you are a MISERABLE, angry human being. Regards! (sic)" Iggy finished.
