Rihanna - No Love Allowed Bass

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

G------------------------------|
D------------------------------|*
A----4-----3----1rr---1111-----|*
E--2r--2-11--4-1----1----------|

F-Bb tuning

G-------------------------------|
D-------------------------------|*
Bb----3-----2----0rr---0000-----|*
F---1r--1-00--3-0----0----------|


Again I apologize if this looks wretched.
