The Bajan singer is known for tweeting all sorts of snaps of her body, but this time she's shown off a bit more of herself in order to reveal to the world her new inking.

RiRi's new body art of Goddess Isis sits neatly directly below her boobs, with the mythical figure's headdress poking up between her breasts.

And the popstar posted a picture of the X-rated tattoo on her Twitter page, to make sure the whole world has seen her new body accessory.

Ri explained that her new body art isn't just a decoration for her boobs - it's a dedication to her grandma.

She posted: "Goddess Isis- Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1lo".

The 24-year-old's beloved grandmother passed away in July - and Rihanna was very open about her devastation at losing her.

Aside from gazing headlong at Ri's breasts this morning, we're finding ourselves wondering what on earth will happen to the pretty sketch if her cleavage sags a little over the years.

But we guess she's such a goddess she probably won't have that kind of normal people's problem.

Meanwhile the global star made us swoon as she flirted her way through her performance with Coldplay in last night's Paralympics Closing Ceremony.

And she teased hit back at Piers Morgan, much to the Twitter audience's amusement, after he told her she needed to grow her hair again quickly.

She told him he should grow err... his private parts.

Instead of crawling away with his tail between his legs, the famous host seized the opportunity to ask for an interview.

Oo we love a good Twitter break-up/make-up.
