Rihanna -- Check Out Tat Bikini - View Rihanna's Tattoos!
Rockin' her red 'do and skimpy bikini,
Rihanna showed off her curves -- and some new ink on her arm and thigh -- while in Hawaii this weekend.

RiRi is shooting the movie "
Battleship" in Hawaii, so the new tats may be for her role and not permanent.
Either way, we like the way you lie ... in the sun.
