The stars came out for the Valerian premiere on Monday night in Hollywood, and they certainly didn't play it safe in the fashion department.
Rihanna stole the show in her blush-colored Giambattista Valli edgy princess gown which had a short front and a lengthy train with puffy sleeves. She paired the bold look with matching Manolo Blahnik heels that laced up to her knees.
