There seems to be Bad Blood (we had too) between Taylor Swift and a fellow musical act in the US.
It comes as the 32-year-old American singer-songwriter is facing a copyright lawsuit in the US.
The claim's being brought by Sean Hall and Nate Butler, who says the Grammy winner lifted words from one of their tracks - "Playas Gon' Play" and put it in her mega-hit "Shake It Off".
The lyrics, "Players they gonna play" and "haters they gonna hate", feature in the 3LW's "Playas Gon' Play", with similar lyrics found in Swift's 2014 song; "Cause the players gonna play, play, play, play, play and the haters gonna hate, hate, hate, hate, hate".
Swift insists the lyrics of her 1989 album's single were written "entirely" by her and that she's "never heard" of the song, and says she used "common phrases".
And this isn't the first time haters have hated on Swift's lyrical choice, in 2014, songwriter Jesse Braham also claimed that the pop star robbed the lyric in his 2013 song "Haters Gonna Hate" and sought 42 million dollars in damages.
