Beyoncé and Jay-Z swapped their Louis sheets for luxe looks when they stepped out together at the French label's Paris Fashion Week runway show June 20.

For the glitzy gathering, the "Break My Soul" singer glowed bright like a halo in golden silk pajamas. She completed her monochromatic 'fit—which featured a button-down top, high-waisted trousers and a long robe—with oversized sunglasses, a large diamond necklace and stiletto heels. 

As for her bag? Bey cuffed it with a Louis Vuitton monogram purse that included a gold chain strap.

Meanwhile, Jay got into formation in a dashing brown three-piece suit, paired with with sunglasses and black dress shoes.

But the powerhouse couple weren't the only stars who checked up on the Louis Vuitton show, which debuted Pharrell Williams' first collection with the brand as its men's creative director. As seen in a video circulating on social media, Zendaya shared sweet hug with Beyoncé while mingling in the crowd.

And the event proved to be a Roc Nation family affair as Rihanna, who is pregnant with her second child, was also there as the star of Louis Vuitton's latest campaign. Clad in head-to-toe in blue denim, the "Needed Me" pop star bared her growing baby bump as she took a seat in the front row with boyfriend A$AP Rocky.

Other celeb attendees included Kim Kardashian, Megan Thee Stallion, Jared Leto, Naomi Campbell and Miranda Kerr.
