Justin Bieber Crashes High School Prom, Causes Teenage Frenzy

Students from Chatsworth Charter High School in Southern California got a huge surprise when Justin Bieber showed up unexpectedly at their prom on Saturday, April 26.

The Vine and Instagram videos that have been uploaded revealed huge crowds of screaming girls as the 21-year-old "Baby" singer, who wore a black-brimmed hat, walked through the venue. Bieber had a huge smile on throughout the night. He also danced with the lucky students.

After the prom, Bieber tweeted: "@CCHSRoyals always wanted to go to prom. Thanks for having me. #promcrasher :)"

HollywoodLife.com reported that Bieber was on his way to a recording studio, which just so happened to be the same location as the prom. Instead of heading straight to work, Bieber decided to have some fun first and crashed the prom.

The terms of the settlement are completely sealed.
