Rihanna gets new pistol tattoo on her thigh

London: Rihanna has been spotted sporting a life size pistol tattoo on her right thigh while holidaying in Hawaii.

The `Rude Boy` hitmaker showed off her curves in a pretty two piece bikini on Monday, also revealing the new tattoo as she tried her hand at paddle-boarding and kayaking in Honolulu.

The 22-year-old singer already has over a dozen tattoos over her body but this one isn`t of a permanent nature, reported Daily Mail.

The new addition is just a temporary inking for her role in the movie `Battleship`, which she is currently shooting. Rihanna plays a naval officer in the action flick.

Loosely based on the popular board game, the film follows an international fleet coming together to save earth from alien invaders.

It also stars `True Blood` actor Alexander Skarsgard and `Friday Night Lights` star Taylor Kitsch as fellow naval officers alongside model Brooklyn Decker, and is expected to be released in 2012.

No details have been released about Rihanna`s character, although she has been spotted on set wearing a uniform featuring a name tag with the label `Raikes`.
