Nicki Minaj has told Steven Tyler to go 'f**k' himself.
Nicki acts as judge on TV talent show American Idol alongside Mariah Carey and Keith Urban.
Aerosmith rocker and former Idol judge Steven told MTV News that he was confident that the Pink Friday rapper would have 'sent [Bob Dylan] to the cornfield' should the folk singer have appeared on the show today.
He was also dismayed by the lack of 'camaraderie' on the panel, ostensibly referencing Nicki's recent feud with Mariah.
Nicki is upset by Steven's comments.
"You assume that I wouldn''t have liked Bob Dylan? Why? Black? Rapper? What? Go f**k yourself and worry about yourself babe," Nicki wrote on Twitter.
"I understand you really wanted to keep your job but take that up with the producers. I haven''t done anything to you. That''s a racist comment."
Nicki also hit out at The View host Barbara Walters recently.
The TV presenter waded into the feud by claiming that Mariah had told her Nicki said she would 'shoot that b***h'.
"Let''s make [Steven] a shirt that says ''No Coloreds Allowed,'' then escort him down [to] Barbara Walters so he can tell how he was threatened [with] guns,' Nicki tweeted.
"When Steven [first] went on ''Idol'' he was ridiculed by his peers & fans alike. Called a sell out. So what does he do? Ridicule the next judge. (sic)"
