Which Celeb Has a Gun Inked on Her Thigh?

Starlet shows off her latest tattoo while vacationing in Hawaii

We've lost count of how many tattoos this star has!

Just this weekend, she showed off yet another while sunning herself in a bikini in Hawaii.

It seems this songbird has a thing for weapons...she also had guns inked on her ribcage.

Think you know who's sporting the thigh artillery?

It's Rihanna!

Just last month, RiRi got fresh ink (in French, no less) on her neck.

But the singer isn't only working on her tattoo collection. She premiered her new single "Only Girl" and the title of her new album on Ryan Seacrest's radio show this morning.
