You're insecure
Don't know what for
You're turning heads when you walk through the door
Don't need make up

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...
