Most of the people look at Rihanna as girly girl pop star and somehow having 15 tattoos doesn't really concur with that image, but I'm guessing this is that part "good girl gone bad".
This exotic Maori-inspired hand tat represents strength and love and was done in the traditional New Zealand style on tattooing, using uhi, or chisels to add inked grooves into the skin rather than piercing it with needles and ink. This makes the skin a bit raised and rough rather than a smooth surface. This intricate tribal hand tat probably hurt really, really bad.
Always a Lesson, Never a Failure Tattoo written backwards so she can read it in the mirror. Rihanna explains that this has always been a motto in life for her, not to treat events as mistakes but as lessons to be learned.
Gun carefully inked on her right rib cage... This tat was a bit controversial since it was done in the midst of her issue with her famous ex-boyfriend.
Girly skull :The red or pink bow on top of the cartoonish and rudimentary skull and cross bones really make this adorable tat stand out.
Her newest tat is "Thug Life" written on the knuckles of each of her fingers (not thumbs of course) in white ink. Rihanna’s “Thug Life†tattoo is a tribute to the late infamous rapper TuPac who started the hip hop group Thug Life in 1993 and had a Thug Life tattoo across his stomach. source
