Justin Bieber gatecrashes high school prom

Justin Bieber caused a commotion when he surprised unsuspecting teens in Los Angeles by gatecrashing their high school prom.

The Boyfriend hitmaker turned up unannounced at the Chatsworth Charter High School dance, which was held at the Jim Henson Studios in Hollywood on Saturday night (26Apr15).

Bieber was reportedly heading to a studio in the same complex with his model friend Hailey Baldwin and decided to drop in on the prom.

He took to the dance floor and was mobbed by students as he attempted to bust a few moves, and was soon whisked away from the crowd by his bodyguards.

A number of teens posted videos and photographs of the singer partying with them on social media, with one fan writing on Twitter, "I danced with (Justin Bieber) at my prom."

A message posted on the school's official Twitter account reads, "Justin Bieber showing up at our prom? I think we know who had the best prom this year."

Bieber responded to the tweet and wrote, "Always wanted to go to prom. Thanks for having me. #promcrasher".
