Rihanna is clearly very comfortable in her skin ... and not much else!
The sexy singer hit the red carpet at the premiere of "Battleship" last night in L.A. -- where she flaunted her hot legs and bare back in a very skimpy, backless white dress.
She was joined by co-stars Brooklyn Decker (who also stunned in white), Liam Neeson, Alexander Skarsgard and Taylor Kitsch -- who had a reunion with "Friday Night Lights" alum Connie Britton.
While they all looked pretty great, all eyes were definitely on RiRi and that revealing gown though.
