5 Guys on 1 Piano Perform One Directions “What Makes You Beautiful” [VIDEO]

I'll admit I've never heard of  the ThePianoGuys before today, but apparently they are pretty popular on YouTube, they have over 600,000 subscribers and over 100 million views on their videos.

Their latest video may turn out to be their most popular yet, with all five of 'ThePianoGuys" playing "What Makes You Beautiful" by One Direction on one grand piano.
