During his London concert at Tottenham Hotspur Stadium on Friday, Jay-Z paused his performance to lead the crowd in a "Happy Birthday" serenade for his wife, Beyoncé, who was celebrating her 45th birthday. The audience joined Jay-Z in singing as fireworks lit up the stadium.

Beyoncé appeared on the stadium's Jumbotron, dressed in a black hoodie, smiling and waving to the crowd while they sang to her. The couple, married in April 2008, have three children: 14-year-old Blue Ivy, and 9-year-old twins Rumi and Sir.

The concert was part of Jay-Z's "Jay-Z 30" tour, celebrating three decades since his debut album, "Reasonable Doubt," and 25 years of "The Blueprint." This marked the first of two London dates, with another show scheduled for Saturday night.

Earlier in July, during a three-show residency at Yankee Stadium in New York, Jay-Z brought his wife and daughter Blue Ivy onstage. Beyoncé joined him for a performance of "Can't Knock the Hustle," taking on Mary J. Blige's part, while Blue Ivy played the piano during "Feelin' It."

Separately, Beyoncé recently released a limited-edition "Bey Keeper Collector's Box" for $948.01, with only 500 available. The price was a nod to her birthday, September 4, 1981, and the 20th anniversary of her second solo album, "B'Day." The singer, who achieved billionaire status last year, faced social media backlash over the item's cost.
