Rihanna Gets New Chest Tattoo In Honor Of Her Grandmother

Rihanna just got a new tattoo—and it's pretty big!

In honor of her departed "Gran Gran Dolly" (who passed away earlier this year), Rih got a tattoo of the Goddess Isis that covers the entire area under her breasts.

She tweeted out the picture of her fresh ink, seen above, followed by this comment: "Goddess Isis- Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1love." It looks like she's had it since her show-stopping VMA performance on Thursday, as seen from another pic tweeted out.

What do you guys think?
