Rihanna has unveiled her latest tattoo.

The Bajan beauty uploaded a revealing photo on Instagram and Twitter last night (September 9) that shows a goddess tattoo on her ribcage and body.

The image is of the Egyptian godess Isis, who is said to have been heralded as a perfect mother and wife.

It appears the new piece of art is a dedication to her late grandmother Dolly, who passed away earlier this year.

Speaking about the tattoo, Rihanna said: "Goddess Isis- Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1love."

As previously reported, Rihanna recently took aim at TV personality and journalist Piers Morgan on Twitter after he made a jibe about her new short hair.

Morgan later tried his luck at asking the singer for an interview, with Rihanna appearing to approve the idea.
