After much anticipation, One Direction's latest Four single officially dropped today. But it's already causing major controversy — and not over whether or not Liam Payne actually leaked the track. Instead, an artist has accused the band of copying another song!

Paramore's Hayley Williams slammed "Steal My Girl" on Twitter because of its alleged similarities to the New Found Glory song "It's Not Your Fault."

The "original" song was released in 2006.

Although "The Only Exception" singer later said she didn't hold anything against the 1D guys — only the people who wrote the song — Liam and Louis Tomlinson co-wrote it with some other songwriters! We hope she's not accusing them of plagiarism.

Ouch, that's definitely a serious accusation! But we don't think 1D would ever intentionally copy another song — that's just not their style.

Do you think "Steal My Girl" sounds like "It's Not My Fault"? Sound off in the comments!
