Azealia Banks has accused Taylor Swift and Lady Gaga of copying her work.
The 24-year-old rapper took to Facebook and shared "fun facts" which describe how she believes the 'Bad Blood' hitmaker and 'Pokerface' singer "lifted" her creative ideas and used them in their own music and videos.
Azealia - who was banned from Twitter following a racist and homophobic rant directed at Zayn Malik earlier this year - targeted 26-year-old Taylor first and said: "FUN FACT: "SLAY-Z" is a nickname given to Azealia Banks by one of her fans in 2014. A play on the Z in Banks' name, and her propensity to release consistently awesome music, the nickname was lifted from her twitter account and featured as one of the characters in Taylor Swift's "Bad Blood" video. Azealia Banks reclaimed the nickname upon the arrival of her self-released 2016 mixtape titled "SLAY-Z. (sic)"
Azealia then turned on Gaga and said the eccentric star named her 2013 album after a genre of music she herself had coined, titled "Whitch-Hop".
She said: "FUN FACT: Azealia Banks created her own genre of music called "Witch-Hop." Coined by the success of 2012's Fantasea Mixtape, Azealia considers her music to be inspired by the invisible world. 3 days after "Witch-Hop" was declared by Azealia Banks to be a legitimate genre, Lady Gaga (also a fan of Azealia Banks) suspiciously titled her then upcoming studio album, "Artpop" (sic)"
Azealia's Facebook attack adds to a bad week for Taylor, 26, following a flurry of Twitter posts from her ex-boyfriend Calvin Harris accusing her of trying to "bury" him just like she did to her pop rival Katy Perry.
His burst of tweets followed the revelation his former lover Taylor - who is now dating Tom Hiddleston - had written the lyrics for his and Rihanna's smash hit single 'This Is What You Came For' under the pseudonym Nils Sjoberg.
He tweeted: "She sings on a little bit of it too. Amazing lyric writer and she smashed it as usual.
"Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage.
"I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do ... I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it
"Please focus on the positive aspects of YOUR life because you've earned a great one. God bless everyone have a beautiful day (sic)".
Following Calvin's outburst, Katy waded in on the row and retweeted a post she shared in May 2015 which simply said: "Time, the ultimate truth teller."
