Lizzo says she's never taken a DNA test despite iconic lyric in 'Truth Hurts'

• In 2019, Lizzo became a star following the success of her hit song "Truth Hurts."
• The opening lyric, "I just took a DNA test turns out I'm 100% that bitch," went viral.

Lizzo said that she hasn't taken a DNA test in real life, despite her viral lyric from the hit song "Truth Hurts."

After winning the record of the year Grammy award on Sunday, Vanity Fair reshared its lie-detector interview with the star from last year. The clip, posted on Instagram, focused on one of the opening lines of Lizzo's hit song: "I just took a DNA test, turns out I'm 100% that bitch."

While connected to the lie detector, Lizzo admitted that she hasn't, in fact, taken a DNA test in her life, but she is willing to get one.

When asked whether she was still "that bitch," Lizzo added: "I mean, sometimes yes, sometimes no. You have your ups and downs when being that bitch. That's what being that bitch is all about."

Lizzo's viral lyric, which was trademarked last week by the artist, has led to controversy in the past.

While Lizzo publicly admitted that the lyric was inspired by a meme, that meme was in turn inspired by a 2017 tweet by British singer Mina Lioness.

A year after "Truth Hurts" was initially released, Lioness tweeted that she came up with the line and deserved a writing credit on the song. At the time, Lizzo responded that she never saw Lioness' tweet when making the song.

The Grammy-winning artist responded: "'Truth Hurts' was written in June fyi— someone made a meme on IG that said "I'm 100% that bitch" and we were inspired, I give that meme credit when I talk about making the song. I've never seen ur viral tweet but I'm glad it exists."

However, after receiving backlash from Lioness and fans for trying to trademark the lyric in 2019, Lizzo decided to give the artist a writing credit on the song.

In addition, in 2019, writers Justin and Jeremiah Raisen accused the "About That Time" singer of not giving them credit for developing the lyric. In a now-deleted Instagram post, Justin said that they had participated in an early songwriting session with Lizzo for a song called "Healthy," which went unreleased.

However, they said that the "melody, lyrics, and chords" were taken from "Healthy" and used in "Truth Hurts," including the "DNA test" line, and neither of the brothers was contacted about being credited.

Lizzo's lawyers refuted this claim and the singer herself wrote on Instagram: "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 [a music producer], and my tears."
