(Photo by Jordan Strauss/Invision/AP) Rihanna has chosen an … interesting way to honor her late grandmother, Gawker reports. The singer yesterday posted a kinda-NSFW photo of a new, very large tattoo (apparently of the goddess Isis) located under her breasts. She also posted the accompanying message, "Goddess Isis- Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1love." Rihanna's grandma died over the summer.
