Harry Styles has been broadening his career recently, with collaborations in the works with both Ariana Grande and Ryan Tedder. While the 1D boy bander will always be a beloved member of One Direction, we're super psyched to hear his upcoming collabs with these A-list pop stars. Which Harry Styles collaboration are you most excited for?

It's safe to say that both Directioners and Arianators flipped when we reported that Harry Styles wrote a song for Ariana Grande. The song's title ('A Little Bit of My Heart') is swoon-worthy enough alone, but the fact that it was co-written by Styles and will be sung solely by Grande, with her killer, raspy vocals, just sends us into a frenzy. This is one tune we absolutely cannot wait to hear.

Styles also recently worked with Ryan Tedder of OneRepublic, an incredibly talented songwriter and producer who has worked with numerous A-listers (including Taylor Swift and Adele). So, of course, it was about time that Tedder sat down with the curly-haired cutie. According to sources, the pair "have been working on new material together," and they share a "mutual appreciation" for one another. This is one seriously sick collab that we don't want to miss!
