Chatsworth Charter High School is claiming they had the best prom of the year, after their dance was crashed by Justin Bieber.

Bieber was headed to a studio next door to where the prom was held and decided to pop by.

He may have "crashed" the prom, but his presence was quickly welcomed by the high school girls!

Twitter quickly flooded with tweets from the excited high schoolers who got the chance to dance with Bieber when he entered the party. When Bieber's presence was noticed by the DJ, his hit song "Baby" started blaring through the speakers at the prom.
