Justin Bieber Dodges Water Bottle From Crowd After Refusing to Sing 'Despacito': 'I Don't Even Know It'

While fans may know the lyrics to Justin Bieber's guest spot on the Luis Fonsi and Daddy Yankee hit "Despacito" word for word, it seems that the star isn't quite up to speed.

The Biebs refused to sing the primarily Spanish-language remix while performing at Summerburst Festival in Stockholm over the weekend -- and almost got struck by an attendee's water bottle for it.

"I can't do 'Despacito,'" Bieber admitted onstage after an audience member requested the track. "I don't even know it."

While some crowd members continued to cheer, one pelted a water bottle at Bieber, just missing the singer's head. "Don't throw things at me, please," Bieber responded calmly.

It's not the first time "Despacito" has brought Bieber trouble: When he tried to perform the Song of the Summer contender at New York City club 1OAK in May, fans caught the singer ad-libbing "I don't know the words, so I say 'Dorito,'" in between mumbled lyrics. 

Fonsi, for one, has forgiven Bieber before for messing up the lyrics, admitting himself that "the chorus is not easy to sing." And none of this has diminished the success of the song, which is currently leading the Billboard Hot 100 for the fifth consecutive week.
