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 and Joe:
Baby you light up my world like nobody else (Joe: 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 what makes you beautiful

Mike:
So [bad word] on
You got it wrong
To prove I'm right I 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 (Joe: 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

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
Oh oh
You don't know you're beautiful
Oh oh
That's what makes you beautiful

Joe with Artie:
If only you saw what I can see
You'll understand why I want you so desperately (Artie: desperately)

Oh oh
You don't know you're beautiful
Oh oh
That's what makes you beautiful.
