The star made a quick trip to the festival for the premiere of the director’s “Highest 2 Lowest.” A surprise was waiting.

Rihanna and A$AP Rocky had to break out their trusty umbrella at Monday night's (May 19) rainy Highest 2 Lowest world premiere at France's Cannes Film Festival. Rocky wore a black suit, black Ray-Bans and a full set of grillz to the premiere of the Spike Lee-directed film - in which he co-stars opposite Denzel Washington - while Rihanna showed off her growing baby bump in an electric-blue dress with strategic cutouts and a scarf tie at the neck.
