A snippet of Justin Bieber's unreleased reggae song has surfaced online. The song was reportedly played during the "Love Yourself" hitmaker's visit to a London nightclub following his performance at the V Festival on Saturday night, August 20.

A fan, who recorded part of the unnamed track, posted the tropical-tinged song on Twitter. It's unclear when the song was actually made, but some fans speculated it was recorded for Justin's latest album "Purpose".

During his V fest performance at Hylands Park in Chelmsford, Justin was blasted by concertgoers for his bad lip syncing. A user tweeted, "Loved #VFestival, but #JustinBieber was the worst performer I've ever seen live- miming 95|percent| & terribly. Lazy, disappointing & insulting." A second user wrote, "Gutted! I love love love Justin Bieber but tonight at V he was miming. Not cool."

"I think @vfestival forgot to turn @justinbieber's mic on tonight... P**s poor live set from bieber," a third user posted. "Nah @justinbieber is miming at V Fest. I ain't paid £80 for a ticket to his tour to listen to his CD and see him run around the stage," shared another concertgoer.

Despite the backlash, Justin shared a photo from his Saturday show and thanked fans for their support.
