Lyrics:

Joe:
You're insecure
Don't know what for
You're turning heads when you walk through the door
Don't need make up
To cover up
Being the way that you are is enough

Rory:
Everyone else in the room can see it
Everyone else but you

Artie:
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, 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, you don't know you're beautiful
Oh oh, that's what makes you beautiful

Mike:
So c-come on
You got it wrong
To prove I'm right I'll put it in a song
I don't know why
You're being shy
And turn away when I look into your eyes

Rory:
Everyone else in the room can see it
Everyone else but you

Artie:
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, you don't know you're beautiful

Joe:
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, you don't know you're beautiful
Oh oh, that's what makes you beautiful

Sam:
Nanananana...
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

All:
You don't know
Oh oh, You don't know you're beautiful

Artie:
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, you don't know you're beautiful

Joe:
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, you don't know you're beautiful
Oh oh, you don't know you're beautiful
Oh oh, that's what makes you beautiful
