Battleship's leading ladies Rihanna and Brooklyn Decker knocked it out of the park in the fashion department today as they attended the Australian premiere of the film at Luna Park in Sydney.

Escorting the lovely ladies was hunk Taylor Kitsch, who looked equally wonderful in a suit.

Yesterday, the cast and crew of Battleship hopped a yacht and explored the views while cruising down  Sydney Harbour. They definitely seem like a close-knit group! 

The movie comes out May 18.
