Barbadian beauty Rihanna already has more than 15 tattoos, including a handgun on her ribs, a pistol on her thigh, and stars on the back of her neck. But over the weekend, she added the most elaborate one yet to her collection -- a tattoo of a Goddess, tattooed around her rib cage and beneath her breasts.

She closed the 2012 London Paralympics this past weekend, and debuted her latest tattoo in a sheer red outfit and later, a sheer black top. She was joined by Coldplay and rapper Jay-Z, to end the 11-day event.

According to the Daily Mail, around 2.7 million tickets were sold for the Games this year. During the closing ceremonies, International Paralympic Committee president, Sir Philip Craven said, "these Games have changed us all forever."

Rihanna's newest tattoo is in honor of her grandmother, Clara "Dolly" Brathwaite, who lost her battle with cancer in July.

The "We Found Love" singer posted a picture of the new body ink to her Instagram account, with the caption, "Goddess Isis-Complete Woman-Model for future generations- #GRANGRANDOLLY- always in and on my heart #1love."

The picture already has over 148,000 "likes" by those who follow Rihanna's account. The tattoo features the face of an Egyptian goddess in the middle of Rihanna's chest, and the wings are spread across the singer's rib cage.

When Rihanna's grandmother passed, Chris Brown, Rihanna's ex-love, also expressed his condolences via Twitter. "Praying for family and the lost loved ones. She was like my grandmother. Love you GRAN GRAN! RIP" he wrote.

Rihanna recently won the Video of The Year Award at the MTV VMA awards, where she and Brown briefly kissed on the lips and warmly embraced, just weeks after she told talk show host Oprah in a candid interview, "we love each other and we probably always will."

The kiss did not seem to please Karreuche Tran, Brown's girlfriend of one year, who after the show tweeted a photo with the caption, "Treat Your Girl Right."
