Justin Bieber shocked an entire prom full of teens in L.A. when he crashed their prom and proceeded to dance with some of the high school girls in attendance there.

It was at Chatsworth Charter High School on Saturday night that Bieber showed up unexpectedly (at least unexpected by the teens–it’s uncertain if the faculty knew he’d be arriving). It’s said that Justin Bieber made some of those young girls swoon.

During and after the prom, word of Bieber’s visit was a hot topic on Twitter, with many Tweeting their excitement and video clips of the celebrity guest. Justin Bieber retweeted several of their messages.

It’s not unheard of for Justin Bieber to show up to events or places like children’s hospitals when he is in town. The ‘As Long As You Love Me’ singer very clearly enjoys making his fans happy. Despite his recent two-years worth of inappropriate behavior, it’s obvious he has a big heart.

Can you even begin to imagine how excited the teens at this high school prom must have been when Justin Bieber showed up to help them dance the night away? It was no doubt even more exciting for those he actually danced with.

Kudos to Justin Bieber for making the Chatsworth Charter High School prom such an incredibly memorable occasion.
