Fans love a good song leak—especially one between star-crossed lovers. So it was a big deal when an unexpected duet from Justin Bieber and Selena Gomez hit the Internet last night. The track, titled "Strong," features stripped down vocals and lovelorn lyrics such as "What should I do? Should I go? Who do I talk to? Nobody knows. Who knows the answer to all of my questions? When will I get over this?" from Bieber, with Gomez singing, "Wishing I was better at this damn thing 'cause it's just been too long and I can't change." 

The fact that this exists at all is bound to have everyone buzzing until the two singers talk about it—and probably long after, as well. Listen to the track below:
