Sorry in advance if this is confusing, this is my first tab.

Single Ladies (acoustic)

CAPO: 2nd FRET

For the strumming pattern listen to Lelia Broussard's verison:

(I'm not Lelia Broussard btw. haha)

There are two chords and they are all the same for the intro, verses, and chorus. 
They are: A and D5

For the Bridge:
I =    X46654

II =   X24432

III =  X024XX

IV=    244322

I                     II
Don't treat me to the things of the world
III              
I'm not that kind of girl
IV
Your love is what I prefer, what I deserve

I                 II
Here's a man that makes me then takes me
    III                          IV
And delivers me to a destiny, to infinity and beyond
IV
Pull me into your arms, say I'm the one you own
If you don't, you'll be alone
And like a ghost Ill be gone

Then back to A and D5
