The Wild Thoughts singer stunned at the European premiere of her new movie Valerian And The City Of A Thousand Planets, wearing the jaw-dropping red dress.
The floor-length dress by Giambattista Valli featured an off-the-shoulder neckline and long train, from the Italian designer’s autumn/winter ‘17 couture collection.
Even Rihanna made reference to her revealing neckline, writing “eyes up here” on a photo caption on Instagram.
Rihanna stars in the Luc Besson-directed sci-fi movie, alongside British supermodel Cara Delevingne, who also walked the blue carpet.
But the $180 million budget movie has so-far bombed at the box office, raking in $17 million, trailing behind Dunkirk ($50.5 million), according to the Daily Mail.
Valerian And The City Of A Thousand Planets opens in Australia next month.
