Singer Rihanna shows off her big cleavage at ‘Valerian and The City Of a Thousand Planets’ premiere in London, 07/24/2017.

Looking hot in a red eye-popping low-cut scarlet gown, Rihanna made reference to her revealing neckline, writing “eyes up here” on a photo caption on Instagram.

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.
