Rihanna has honoured her late grandmother with a sprawling goddess tattoo across her ribcage. The singer was left devastated earlier this year when she lost her beloved relative Dolly following a long battle with cancer. She has now paid tribute to her late grandmother with an inking comparing her to an Egyptian goddess. The star posted a picture of the tattoo on her Twitter page over the weekend, which shows Isis kneeling with her knees spread. Alongside the picture, Rihanna tweeted: “Goddess Isis – Complete Woman – Model for future generations – #GRANGRANDOLLY – always in and on my heart.”
