Agosto 19 de 2011, fue la fecha en que esta banda subio a Youtube el video  oficial de su primer Single, conocido como  "What Makes You Beautiful" que fue un gran exito alrededor del  mundo.
You’re insecure 

Don’t know what for 

You’re turning heads 

When you walk through the do-o-or 

Don’t need make up 

To cover up 

Being the way that you are is en-o-ough 

Everyone else in the room can see it 

Everyone else but you 


Baby you light up my world like nobody else 

The way that you flip your hair gets me overwhelmed 

But when you smile at the ground it ain’t hard to tell 

You don’t know oh oh 

You don’t know you’re beautiful 

If only you saw what I can see 

You’ll understand why I want you so desperately 

Right now I’m looking at you and I can’t believe 

You don’t know oh oh 

You don’t know you’re beautiful 

Oh oh 

That’s what makes you beautiful 


So c-come on 

You got it wrong 

To prove I’m right I put it in a so-o-ong 

I don’t know why 

You’re being shy 

And turn away when I look into your ey-e-es. 

Everyone else in the room can see it 

Everyone else but you 


Baby you light up my world like nobody else 

The way that you flip your hair gets me overwhelmed 

But when you smile at the ground it ain’t hard to tell 

You don’t know oh oh 

You don’t know you’re beautiful 

If only you saw what I can see 

You’ll understand why I want you so desperately 

Right now I’m looking at you and I can’t believe 

You don’t know oh oh 

You don’t know you’re beautiful 

Oh oh 

That’s what makes you beautiful 


Na na na na na na naaaa na na 

Na na na na na na 

Na na na na na na naaaa na na 

Na na na na na na 


Baby you light up my world like nobody else 

The way that you flip your hair gets me overwhelmed 

But when you smile at the ground it ain’t hard to tell 

You don’t know oh oh 

You don’t know you’re beautiful 


Baby you light up my world like nobody else 

The way that you flip your hair gets me overwhelmed 

But when you smile at the ground it ain’t hard to tell 

You don’t know oh oh 

You don’t know you’re beautiful 

If only you saw what I can see 

You’ll understand why I want you so desperately 

Right now I’m looking at you and I can’t believe 

You don’t know oh oh 

You don’t know you’re beautiful 

Oh oh oh 

You don’t know you’re beautiful 

Oh oh oh 

That’s what makes you beautiful
