Indie band Sleigh Bells took to Twitter on Monday to call out Demi Lovato for allegedly sampling not one, but two of their songs.

The musicians are claiming that the pop star's new track, "Stars," takes from both "Riot Rhythm" and "Infinity Guitars," which were both songs from their 2010 debut album, Treats.

"@ddlovato Demi Lovato flattered you guys sampled Infinity Guitars & Riot Rhythm for 'Stars' but we were not contacted," Sleigh Bells tweeted. "Gotta clear those."

Give all three songs and listen and see if you can spot any similarities:

"Infinity Guitars"

"Riot Rhythm"

"Stars"

This isn't the first time Lovato has been accused of ripping off another artist. Upon the release of "Cool for the Summer," people started to claim that the track sounded similar to Katy Perry's "I Kissed a Girl" and Jessie's J's "Domino." Perry's lyrics in "I Kissed a Girl" were especially compared to Lovato's summer hit.

The former Disney star responded via Twitter to the allegations, writing: "Sounds nothing like it and with all the advances we've made in the LGBT community..."

Both "Stars" and "Cool for the Summer" appear on the 23-year-old singer's new album, Confident.

Lovato seemed very proud of the songs when she spoke with ET at the MTV Video Music Awards in August. "I wanted something that was going to best represent the album title, where I'm at today and the music," she said of naming her album. "I've never been more confident in my life and it was the perfect album title."
