Rihanna wore a Stella McCartney jumpsuit for today's premiere of Battleship in Sydney. She was joined on the red carpet by leading man Taylor Kitsch, as well as costar Brooklyn Decker. Brooklyn Decker's style has been on great display so far during her action movie press tour, and today's gold lamé-sleeved J. Mendel gown didn't disappoint. Brooklyn looked refreshed after a fun weekend with two girlfriends. She had a visit from pals Chrissy Teigen and Erin Andrews, and the trio spent the Easter holiday together sightseeing, lounging in bikinis, and fitting in workouts. The girls even shared a scenic boat tour with Rihanna yesterday. Today, though, was all about business for Rihanna and Brooklyn, who spent the afternoon doing phone interviews.
