It's safe to say 'Despacito' is going to be our official 'song of the summer'. This song is actually a few months old. It was originally released by Luis Fonsi and Daddy Yankee only. Then, a remix was made where they added Justin Bieber. You know what that means. INSTANT HIT! The song has totally BLOWN up. Justin Bieber was hanging out at a club here in New York City when his song came on. He got on the mic and kind of tried to sing it. But he did not remember the words! Watch the video below.
