This ridiculous video was posted online in the summer, but has only gone viral this weekend, amassing over half a million views!

Apparently, a little brother snuck into his sister’s room to crank up some Britney Spears and work it like no one was watching.

Except his sister was hiding in the closet, recording all of his sweet moves. 

The clip has appeared on HuffPost, TastefullyOffensive, and SayOMG
