Rihanna revealed on Twitter her latest tattoo, shown in an unpublished photo from her Rolling Stone cover story.

In the picture, taken by famed photographer Terry Richardson, the Bajan beauty is wearing a white tank top and under her left arm there is a tattoo of a Queen Nefertiti figure head. The ink job is positioned just above another tattoo she has- the Arabic reading of "Al Hurria fi Al Maseeh," which means "freedom in God" or "freedom in Christ."

The Nefertiti tattoo is likely her 15th ink job. The Diamonds singer debuted her 14, a tribute to her late grandmother, in September of an Egyptian goddess inked just below her breasts. She posted the image to her Instagram page for her millions of followers to see on Sept. 9.

"Goddess Isis- Complete Woman - Model for future generations- #GRANGRANDOLLY - always in and on my heart #1lo," Rihanna wrote at the time.

The Grammy winner got it done in the Soho area of London where she performed for the Paralympics closing ceremony during the London 2012 Games.

Rihanna's many tattoos include a symbol for her astrological sign Pisces behind her ear; a falcon, a gun, music notes, the word "Love" one finger and "shhh!" on another. She also has a trail of stars on the back of her neck as well as the words "Never a failure, always a lesson" across the front of her shoulders written backwards so she can read it properly when standing in front of the mirror. She reportedly had a Tupac-inspired "Thug Life" tattoo across her knuckles at the Shamrock Social Club in Los Angeles,

She reportedly tweeted "All these b****es screaming that 2pac back ? #THUGLIFE" at the time.

Rihanna also has a tattoo of the Roman numerals "XI•IV•LXXXVI" - which signifies 4.11.1986, the birth date of her best friend Melissa Forde - on the front of one of her shoulders. Forde also has a matching tattoo of Rihanna's birthday. Rihanna has the name of her fragrance Rebelle Fleur on her neck. Translated from French to English, the phrase means "rebel flower."

Her largest tattoo, which is rarely seen, stretches from above her waist down her hips toward her butt. It is a Sanskrit prayer taken from a Hindu scripture.
