There's been a lot of speculation that Alex & Sierra's song "I Love You" was actually written by Harry Styles, and now the X Factor duo has basically confirmed it. The One Direction singer reportedly wrote the track under a pen name, and while the couple won't spill if Hazza is actually Mick Greenberg, they hinted that the song written about a relationship with Taylor Swift!

“We were told that Mick Greenberg wrote it. That’s what we were told, that’s all we know,” Alex said. "It could be Shaq! We don’t know… Shaquille O’Neil might have written it.”

“Maybe Mick and Taylor are really good friends… Maybe Mick & Taylor had a fling!" they joked.

Based on their reaction, it definitely seems like they don't want to spill that the 1D guy really wrote their song. But they're probably sworn to secrecy!

"I Love You" does seem to have a lot of references to Taylor's music. In one part, the songwriter says, "I won't trouble you no more," seemingly referencing "I Knew You Were Trouble" (which was written about Harry).

We definitely think it's likely! And if so, it means that the 1989 star isn't the only one writing confessional tracks about their relationship.

Do you think Harry wrote "I Love You" About Haylor? Is Mick his secret pen name? Tell us in the comments!
