Hey, so I downloaded the song today, and I fooled around with some chords and I came up
these...Not sure about the Bridge though.

Tuning: Standard

Chords:

E- (022100@1)[0 2 2 1 0 0]
B- (x2444x@1)[0 2 4 4 0 0]
Gb - [2 4 4 3 2 2]


The verses and the chorus go like this:

Edo-op, (022100@1)do-op)
   BLets (x2444x@1)make it happen, shorty
Gb(do-op, (244322@1)do-op)

B (x2444x@1)  GbIt's (244322@1)gotta be now
E(do-op, (022100@1)do-op)
    BEven (x2444x@1)though we shouldn't
      Gb (244322@1)         B (x2444x@1)          ESummer (022100@1)girl, you're right for me

Just the same E B Gb B Gb Pattern over and over again through the verses and chorus. I 
made this in about 10 min, so there could be many mistakes, leave a comment and let me 
if you find any.
