Beyoncé’ Celebrates Rumi, Sir Carter at Cowboy Carter Tour

Beyoncé can get the world to stop in honor of her kids’ birthday.

The proof was in the crowd’s reaction during night four of the Cowboy Carter tour at Tottenham Hotspur Stadium in London on June 12. Beyoncé and Jay-Z’s twins Rumi Carter and Sir Carter marked their 8th birthday on the day of her concert—and the singer made sure the audience showed them some love during her performance of “Protector.”

Beyoncé held Rumi close while she serenated her, before her oldest daughter Blue Ivy Carter, 13, joined them at the front of the stage. Honoring her kid’s special day, the “Dangerously in Love” singer told the crowd, “Everybody say happy birthday, Rumi.”

As the crowd repeated the phrase back, Rumi excitedly waved in their direction while her big sister sweetly touched her chin. Though he wasn’t on stage with his sisters, Beyoncé made sure her son felt the love telling the crowd, “Say happy birthday, Sir,” before adding, “I love you.”
