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 eno-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 could see
you'd 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 [bad word] 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 in to your ah-ah eyes
Everyone else in the room can see it
Everyone else but yo-ouuu
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
