Two music superstars have been lighting up Paris this week: Beyoncé with her massive Cowboy Carter tour, and Miley Cyrus promoting her latest album, Something Beautiful—both turning heads with a series of vintage-inspired street style looks. Last night, they took things to the next level, teaming up for a surprise performance that left the city buzzing—complete with matching gold outfits.

During her June 19 show at the Stade de France, Beyoncé brought Miley onstage, saying, “I love y’all so much. I’m super excited because I wanted to do something very special for you. Give it up—I’m so grateful to sing with you, Ms. Miley Cyrus!” The duo then performed “II Most Wanted” from Cowboy Carter, their Grammy-winning country collaboration, sending the crowd into a frenzy.

Both artists dazzled in head-to-toe gold sequins—Beyoncé in a fringed bodysuit with a jeweled neckline and cowboy boots, while Miley rocked a shimmering crystal catsuit with stiletto boots. Their shared fashion motto? Go big, go bold, go gold.

Beyoncé’s tour has been a showcase of high-fashion Western glam, with looks styled by Shiona Turini, Ty Hunter, and Karen Langley. She’s worn everything from a white Mugler bodysuit with diamond-studded chaps to Burberry’s sequined plaid and a denim-printed Roberto Cavalli catsuit. Even her daughter, Blue Ivy, has joined the spectacle in custom rodeo-inspired outfits, including a gold gown and a green Burberry bodysuit to match her mom.

Though their style choices differ—Beyoncé favoring Mugler and Ferragamo, Miley leaning into Alaïa and Versace—both share a love for over-the-top glamour, often meeting in the middle with Schiaparelli and Cavalli.

With the Cowboy Carter tour now past its halfway point, Beyoncé heads back to the U.S. for stops in Houston, D.C., Atlanta, and Las Vegas, wrapping up on July 26. After Miley’s surprise guest appearance—the tour’s first—fans can only hope for more star-studded collaborations (and more glittering fashion moments) when the show returns stateside.
