Rihanna and A$AP Rocky are true blue.

The musical power couple were among the many stars in attendance at Pharrell Williams' debut runway show as Louis Vuitton's men's creative director on Tuesday in Paris — and were in perfect style sync for the outing.

While the pregnant Bad Gal bared her baby bump in a checkered denim bra top and jumpsuit, her longtime partner matched in a denim jacket and baggy jean shorts covered with the brand's logo.

Both topped off their looks with likeminded blue bejeweled beanies and plenty of bling; Rihanna, for her part, rocked a $700,000 watch choker from jeweler to the stars Jacob & Co.

Rihanna and Rocky are currently expecting their second child together after welcoming son RZA, now 13 months, in May 2022.

The duo were far from the only A-listers in attendance at the Vuitton show; Kim Kardashian, Beyoncé, Jay-Z, Zendaya and Naomi Campbell were among the others who turned up to support Pharrell.

Rihanna stars in the house's new spring 2024 campaign, her growing belly front and center.

In the ad, she models an unbuttoned leather jacket and layered necklaces, her arms loaded up with the brand's iconic Speedy bags in various colors.

The "Diamonds" songstress is famous for her marvelous maternity style, with recent standout looks including everything from a faux fur crop top to vintage Chanel.
