Paramore vocalist Hayley Williams has called out British boyband One Direction for allegedly ripping off American band New Found Glory's song "It's Not Your Fault," according to The Independent.

The 26-year-old vocalist sent a series of tweets accusing the boyband of plagiarizing the band's 2006 tune in their new single "Steal My Girl." Williams has been in a relationship with New Found Glory's guitarist and chief songwriter Chad Gilbert since 2008.

"Beginning of that new 1D song couldn't sound any more like the beginning of New Found Glory's 'It's Not Your Fault,'" she said in one tweet. Williams was pertaining to the piano hook heard on the intros of the two songs.

Recognizing the notorious protectiveness of the boyband's followers over the group, she wrote: "I realize I'm gonna get hate from a very large fanbase for that, but really, it has more to do with whoever pitched or co-wrote the song."

Gilbert chimed in on Twitter and seconded Williams' observation.

"Props to the One Direction 'Steal My Girl' single for reworking the 'It's Not Your Fault' piano part into a Top 40 single. Let me get a cut," he wrote.

The guitarist later doubled back and said his tweet was only a joke. "Wow did not realize this was gonna be a story. It's not a story. My original tweet was a joke anyway. Music influences music. No one cares," he tweeted.

Nevertheless, the deluge of tweets from One Direction fans continued, causing the guitarist to ask the boyband's followers to stop sending him tweets.

"All you One D'z nuts fans. Second period is starting. Get to class and stop tweeting me. It's not their fault so please stop your tweeting now," Gilbert said.

Ultimately, he sent a tweet to One Direction's Twitter regarding the matter. "Your fans spew the most racist/homophobic/sexist hate I have ever seen on the Internet... You have a platform to change that," he wrote.

As SPIN notes, the intros to the two songs feature the same melodic hook and patterns. But for all the debate, the magazine also points out that the hook the two songs share follows the piano riff on the intro to Journey's 1985 smash hit "Faithfully."
