Rihanna - No Love Allowed Chords & Tabs

This is my first tab so sorry if it looks dodgy

There's some subtle differences as the song goes on but here's the gist of it. I found 
it easier to play if you tune up a half step so E to F, A to Bb, etc but I'll put both 
the half step version and the standard version

Standard tuning

D------------------------------|*
A----4-----3----1rr---1111-----|*

F-Bb tuning

Again I apologize if this looks wretched.
