I searched 5 different sites and all of the tabs for this song were horribly incorrect 
here is my by ear interpretation.

Intro: A  D, A  D   4x

VERSE 1:
A              D         A
We go out to a party somewhere, the moment we walk in the door

A                D         A
We both stop and everybody stares, she don't what they're staring for

CHORUS:
A         E          D
She don't know she's beautiful    (never crossed her mind)

A         E          D
She don't know she's beautiful    (no she's not that kind)

A         E          D                              
             A
She don't know she's beautiful, though time and time I've told her so

PLAY INTRO ONLY 2x INSTEAD OF 4:

A                  D                 A
There she goes just walking down the street and someone lets a wistle out

A                  D            A
A girl like her she just cant's see, what the fuss is all about

CHORUS:

INSTRUMENTAL:  A   D   A   D   A   D  A   E   A   D   A   D

A                    D         A
Mornin comes and her hairs all mess thats when she thinks she looks her worst

A                      D          A
Its times like this she dont know why, I cant take my eyes off her

CHORUS:  PLAY UNTIL FADE OUT
