Siblings have a habit of embarrassing you and, unfortunately for him, this boy found that out the hard way.
His sister decided to take full advantage of the fact that he was dancing to Britney Spears in her room by videoing the whole thing.
The clip, which was uploaded to YouTube during the summer but went viral at the weekend, has over half a million views.
We don't know what we love more though, his moves or his reaction when he sees her recording him...
