Pop sensations Ariana Grande and Harry Styles have crossed paths!

Is there anything more exciting than some of our favorite pop idols coming together to create collaboration perfection? We're still trying to catch our breaths from the news of Katy Perry and country star Kacey Musgraves pairing up for the 'CMT Crossroads.'

Don't worry, Directioners, Styles isn't taking off on a solo career just yet. According to the American Society of Composers, Authors and Publishers (ASCAP), Styles has been busy penning new music -- you know, somewhere in between debuting a new perfume, selling out a world tour and buying a home in sunny Los Angeles.

Along with a Swedish songwriter who also shares the writing credit, Styles is listed as a writer for a song whose title alone makes us swoon over the sweet choice of words: 'A Little Bit of My Heart.'

Grande must have been taken by the British boy band member's song as well, because she has since recorded 'A Little Bit of My Heart' and is now listed by ASCAP as its sole performer.

Grande is no stranger to working with other artists, as seen by her acclaimed 'Almost is Never Enough' duet with then-boyfriend Nathan Sykes, and her more recent but sadly delayed 'Don't Be Gone Too Long' with Chris Brown. Do you think the Grande-Styles team will outshine the others?

Personally, we're dying to hear what romantic lyrics Styles has packed into the tune and how Grande's powerful voice will transform them.
