Lizzo has denied claims from three men that they helped to write her single Truth Hurts.
The song was originally released in 2017 but became a chart hit this year.
The musician has dismissed the men's allegations that they collaborated on the track and has filed a lawsuit asking a judge to declare they have no copyright on it.
Lizzo wrote on her Twitter: “The men who now claim a piece of 'Truth Hurts' did not help me write any part of the song. They had nothing to do with the line or how I chose to sing it. 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.”
British singer Mina Lioness has been given a writing credit for the song Truth Hurts.
The row started after Lizzo wanted to trademark the phrase "I just took a DNA test turns out I'm 100% that...".
Mina Tweeted a similar phrase back in 2017, however Lizzo claims never to have seen it.
"In 2017, while working on a demo, I saw a meme that resonated with me... I later used the line in Truth Hurts... I later learned that a tweet inspired the meme", Lizzo said on Twitter.
"The creator of the tweet is the person I am sharing my success with..."
While she didn't name her, Mina responded shortly after with a tweet thanking Lizzo and her team.
