Beyoncé Knowles-Carter launched the international leg of her "Cowboy Carter" tour, and many fans were excited to see a set of special twins dancing behind her.

The Grammy-winning singer kicked off her June 5 London show on the Cowboy Carter and the Rodeo Chitlin' Circuit Tour at Tottenham Hotspur Stadium around 7:39 p.m. local time — the earliest yet. And fans in the stadium and watching online were in for a treat when they noticed Les Twins — Laurent and Larry Nicolas Bourgeois — dancing onstage with her.

Fans instantly flooded social media with excitement. One fan wrote, "Omg they are back. I hope they come to the DC. show." Another exclaimed, "OMG THE TWINS," and many others cosigned.

Born in Sarcelles, France, Les Twins have become known as Beyoncé's other set of twins, along with her 7-year-old children Sir and Rumi Carter. Les Twins have collaborated with her on numerous occasions, dancing alongside her on major stages, tours and videos. Some of those include the Mrs. Carter Show World Tour in 2013, Beychella in 2018 and the Renaissance World Tour in 2023.

On the "Cowboy Carter" tour, daughter Rumi has been making nightly appearances to wave to the crowd along with her sister, Blue Ivy Carter, during the song "Protector." Sir has not appeared, and neither had Les Twins, until June 5.
