[Joe:]
You're insecure
Don't know what for
You're turning heads when you walk through the d-o-o-or
Don't need make up
To cover up
Being the way that you are is eno-o-ough

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

[Artie and Joe with Rory, Mike & Sam:]
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

[Joe with Rory, Mike, Artie & Sam:]
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

[Mike:]
So c-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 e-e-eyes

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

[Artie with Rory, Mike, Joe & Sam:]
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

[Joe with Rory, Mike, Artie & Sam:]
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

[Sam with Artie, Joe, Rory, and Mike:]
Nana Nana Nana Nana
Nana Nana Nana 
Nana Nana Nana Nana
Nana Nana Nana 

[Sam:]
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

[Rory with Artie and Joe:]
You don't know
Oh Oh

[Joe:]
You don't know you're beautiful

[Artie and Joe with Rory, Mike & Sam:]
Baby, you light up my world like nobody else ([Joe:] nobody else)
The way that you flip your hair ([Joe:] come on!) gets me overwhelmed
But when you smile at the ground ([Joe:] ground) it ain't hard to tell
You don't know
Oh oh
You don't know you're beautiful ([Joe:] ful)

[Joe with Artie, Rory, Mike & Sam:]
If only you saw what I can see
You'll understand why I want you so desperately ([Artie:] 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
You don't know you're beautiful
Oh oh

[Joe:]
That's what makes you beautiful.
