Only Rihanna can pull off ladylike and sexy at the same time, and she showed off that unique talent Wednesday in London. RiRi wore an olive green Alexander Wang dress to a photocall for her new movie “Battleship” and showed that she can go from gorgeous and approachable to sexy and mysterious in just seconds.

Joined by co-stars Brooklyn Decker and Taylor Kitsch, Rihanna looked like she was having a great time at the event. In the film, the singer plays a weapons specialist, so that explains why her nails look like they could be lethal!

What do you think of Rihanna’s chic look? She has many more photocalls and premieres on the way because “Battleship” doesn’t open in theaters until May 18^th.
