Let's get those teen hearts beating faster! One Direction heartthrob Zayn Malik has a long-standing relationship with DJ/"La La La" producer Naughty Boy. They've worked on 1D material together, they've been photographed hanging out together...it's a relationship truly extends from the studio to the streets. 

There are rumors circulating that Malik will return the favor and appear on NB's upcoming album. "I can’t deny the fact that we have made music together," Naughty Boy reportedly told The Sun. "Zayn is going to feature on my next album.

"We’re making music and having fun. This is just like a side gig and I don't think there's anything wrong with it," he continued. "It's a good time for Zayn to showcase what he can really do. I don't think that is being fully exploited with the band because there are five people and it needs to be balanced out."

Fellow 1D member Harry Styles has done some songwriting on the side (penning "Just a Little Bit of Your Heart" for Ariana Grandeco-writing "London Lights" with Meghan Trainor), but Zayn featuring on an album would be the first vocal side gig.

So what do you think? Is this the beginning of the end of One Direction? Is Malik just exploring some of his creative impulses? What does it all mean? Tell us your thoughts in our poll below.
