Holy hotness…ladies and gents are you sitting down for this one!? Shawn Mendes is promising a collaboration with former One Direction member Niall Horan! The buddies, who share more than just a similar taste in women (ahem, Camila Cabello and Hailee Steinfeld) also share a love for music. Not to mention a TALENT for singing and songwriting! We cannot wait to see them collaborate on a new project together ASAP!
