"Despacito" -- you've heard it on the radio in the car on the way to work, watched parodies of it on Facebook and might've even added it to your Spotify playlist, setting it to repeat while you get ready for a night out.
There's no denying that the remixed track, a collaboration between Justin Bieber, Daddy Yankee and Luis Fonsi, is everywhere at the moment.
So imagine the disappointment of Bieber's fans when the 23-year-old politely refused to perform the hit song despite desperate pleas from the crowd at Sweden's Summerbust festival.
"I can't do that [song] specifically. I don't know the words, I can't do it," the superstar told fans.
One fan, however, took their disappointment to a whole new level, hurling a water bottle at the singer's head.
Judging by Bieber's reaction though, we're guessing it's probably not too late for that fan to say sorry.
It's not the first time the Canadian singer has had something thrown at him, in 2013 he stormed off stage after a fan in Brazil also threw a bottle at him.
Bieber previously caused controversy when he performed "Despacito" in New York City's 1 Oak nightclub in May, during which he sang the line "I don't know the words so I sing dorito".
