Over the weekend Justin Bieber was performing in Stolkholm when people started chanting for him to perform 'Despacito'. He replied to them and said "I can't sing that song I don't know the words." One fan was so annoyed that they threw a shoe at him! That's a little over the top! The song is 90% in Spanish. I'm sure he knows his verse...but I wouldn't expect him to know the whole song right?
