Harry Styles co-writes new song with John Legend for 'X-Factor' duo Alex & Sierra amidst solo career and One Direction break up rumors

According to X-Factor contestants Alex and Sierra, Harry Styles is writing new songs with John Legend. These songs are for the singing duo from the X-Factor competition and marks the first time a member of One Direction has worked outside of the boy band. It might have been hard for Harry to turn down the chance with his idol John Legend, but what does this mean for One Direction's future - a future that has recently come under question with rumors of the boys breaking up soon?

"Our favorite [song] is one that Harry Styles wrote with John Legend, it's beautiful and lovely," Sierra revealed. "[Harry] is actually an amazing writer, he's pitched us a few other good ones and they're really good."

Meanwhile, a recent Twitter post from Simon Cowell spoke volumes to Styles' writing talent as well, saying: "Am listening to the Alex and Sierra demos for their upcoming album. Fantastic. It's seriously good. I can't wait for everyone to hear it."

Though he didn't mention Styles by name (probably to avoid this controversy that is starting up), he complimented the songs that he wrote!

A source explained: "It's a testament to Harry's talents that he can work alongside John - who is, without doubt, one of the most gifted songwriters of a generation."  

The Mirror points out: "Harry is credited to 26 songs on the database of American Society of Composers, Authors and Publishers - 18 of which are unheard."

What do you think will come from Harry's songwriting career? Are you worried it will directly affect One Direction's future?
