Rihanna’s gun tattoo is only henna

London: Rihanna’s tattoo of a gun etched on her thigh is only henna.

The 22-year-old Te AMO singer showed off the new body art as she donned a skimpy bikini to take a dip in the sea with pals in Hawaii.

But fans of Rihanna should not fear of her dangerous new image –as it is a henna tattoo, reports the Sun.

It is believed to be for her new movie Battleship - and will disappear after filming.
