Shine bright, indeed.

Rihanna continued her sexy maternity style streak Wednesday, making a cameo at A$AP Rocky’s Spotify concert during the 2023 Cannes Lions Festival on Wednesday wearing a sparkling swimsuit beneath her sheer dress.

Her glittering Oséree “microkini” ($225) was on full display beneath her see-through vintage Jean Paul Gaultier gown — as was her baby bump.

The Bad Gal, who’s pregnant with her second child with Rocky after welcoming son RZA in May 2022, accessorized with padlocked python Tom Ford stilettos.

“She makes pregnancy look so fun,” a fan gushed on Twitter of Rihanna’s latest look, which she also wore to dinner with Rocky at Nespo; the restaurant shared sweet photos of the power couple striking prom-worthy poses on Instagram.

For more Page Six Style …

As exclusively reported by Page Six, Rocky called Rihanna his “wife” during his performance, telling fans, “I’d like to dedicate this song to my beautiful wife in the motherf–king building!”

The rapper performed hits like “Sundress” as his partner smiled and danced along in the VIP section.

Plenty of other celebrities attended the concert, including Tiffany Haddish – who shared a smooch with “Bachelorette” alum Dale Moss, as Page Six exclusively reported – as well as TikTok star Tinx and “Saturday Night Live” actors Chloe Fineman, Bowen Yang, Ego Nwodim and Mikey Day.

The event, which also featured performances from the Foo Fighters and Disclosure, was such a hot ticket that fans attempted to paddle their way in on rafts.

“People were so desperate they literally tried to float their way into the concerts,” a spy told Page Six of the “mayhem.”
