Songwriters Justin and Jeremiah Raisen went public with a plagiarism claim over this song in October 2019. According to The New York Times
, the Raisen brothers, Lizzo, and two other writers, Jesse Saint John and Yves Rothman, came up with a demo called "Healthy" in April 2017 that included the famous line, "I just took a DNA test, turns out I'm a 100% that bitch," which later appeared in "Truth Hurts."
That line was adapted from a 2017 tweet by British singer Mina Lioness that Saint John showed the other writers.
Lizzo responded to the accusations by launching legal action against the Raisen brothers and Justin 'Yves' Rothman. She said in a statement that they didn't help her write any part of the song and had nothing to do with the "DNA Test" signature line or how she chose to sing it.
Lizzo added: "There was no one in the room when I wrote 'Truth Hurts,' except me, Ricky Reed, and my tears. That song is my life, and its words are my truth."
Though Saint John is credited on "Truth Hurts," neither of the Raisen brothers or Rothman are. "We were never contacted about being credited for the use of the parts of 'Healthy' (melody, lyrics, and chords) that appear in 'Truth Hurts,'" the Raisens wrote in a statement.
The Raisens added they have been trying to resolve the dispute since 2017. "We've tried to sort this out quietly for the last two years, only asking for 5% [of the songwriting royalties] each but were shut down every time."
By February 2020, the dispute had not been resolved, so the Raisen brothers and Rothman filed a counterclaim against Lizzo, demanding they be compensated for their contribution to the song.
