Disney-incubated pop star Demi Lovato dropped her latest album, Confident, last month, and Sleigh Bells’ Alexis Krauss and Derek Miller have taken issue with one of the LP’s tracks for similarities to their own catalog.

Sleigh Bells posted a tweet on Monday (Nov. 2), accusing Lovato of using unauthorized samples of the noise-pop duo’s “Infinity Guitars” and “Riot Rhythm” in her own song “Stars”:

Both “Infinity Guitars” and “Riot Rhythm” appeared on Sleigh Bells’ 2010 debut Treats. You can compare all three songs at the bottom of the page.

Lovato's producers Carl Falk and Rami have denied Sleigh Bells' allegations in a statement. "We did not use any samples in Demi Lovato's song 'Stars,'" they told Entertainment Weekly. "Demi was also not involved with the production. She only wrote top line."

Since Treats, Sleigh Bells have issued two more full-lengths, including 2012’s Reign of Terror and 2013’s Bitter Rivals. Last year, they dropped the standalone single, "That Did It," featuring rapper Tink.
