OMG! Did Harry write a special song for Ariana?

Arianators and Directioners, get ready to join forces! According to the American Society of Composers, Authors and Publishers, 1D's Harry Styles co-wrote a song titled, "A Little Bit of My Heart," and Ariana Grande is set to perform it! Unfortch, there's no plans for a duet yet, but we can't wait to hear Ariana belt out Harry's soulful lyrics. We bet Ari is excited, too! Back in January, she told a crowd of fans outside her N.Y.C. hotel that the British hottie was "nice!" Aww- "Hariana" has a perfect ring to it, don't you think?!
