Justin Bieber's refusal to sing Despacito didn't go down well with the crowd at a recent concert.
After a fan requested the song, Bieber admitted on stage:
I can't do Despacito. I don't even know it.
The result ended up with someone chucking a bottle of water at him which narrowly missed his head.
"Don't throw things at me, please," Bieber responded calmly.
It's not the first time Bieber has had trouble with singing the heavily Spanish song. Last month he admitted he didn't know the words to the song, ad-libbing "I don't know the words, so I say 'Dorito,'".
