Iggy Azalea has stepped her feud with Azealia Banks up a notch by blasting her for being a ''bigot'', ''poisonous'' and a ''miserable, angry human being''.

The 24-year-old rapper took to her Twitter account to slam the 23-year-old star for ''bullying others'' after Azealia insisted yesterday (18.12.14) that Iggy's music was ''not excellent'' enough for Grammy recognition after she was nominated in the Record of the Year category for her hit 'Fancy'.

In a series of tweets, she wrote: ''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.

''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 realise yet. Probably never will.

''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's comments come after Azealia opened up in a 45-minute interview on Hot 97's 'Ebro in the Morning' show about how she feels black artists do not get the credit they deserve.

She said: ''I feel like, in this country, whenever it comes to our things, like black issues or black politics or black music or whatever, there's always this undercurrent of kinda like a 'F**k you.'

''There's always a 'F**k y'all n*****s. Y'all don't really own s**t. Y'all don't have s**t.

''That Macklemore album wasn't better than the Drake record. That Iggy Azalea s**t isn't better than any f***ing black girl that's rapping today.

''The Grammys are supposed to be accolades of artistic excellence. Iggy Azalea is not excellent.

''When they give these Grammys out, all it says to white kids is, 'Oh yeah, 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 s**t. You don't own s**t, not even the s**t you created for yourself, and it makes me upset.''

Azealia also blasted Iggy earlier this month for staying silent on ''black issues'' such as the police killings of Eric Garner and Michael Brown.

She wrote: ''its funny to see people Like Igloo Australia silent when these things happen... Black Culture is cool, but black issues sure aren't huh? (sic)''

But Iggy later hit back: ''Theres more to sparking a change than trolling on social media. World issues shouldnt be used as a poor excuse to promote fan battles. (sic)''

This all comes just a few weeks after Azealia - who has also clashed with Eminem and T.I. in the past - insisted she was giving up on feuds because she is a ''lady''.

She said: ''Am I hanging up my fighting gloves? Yeah. I'm a lady. I don't wanna be dealing with that.''
