Beyoncé and Jay-Z showed their love for one another at the Sound of Change concert Saturday in Surrey, England. The event, which was sponsored by Chime for Change, an organization founded by fashion powerhouse Gucci, focuses on eduation, health and justice for women in primarily underprivileged countries.

The 31-year-old star is one of the founding members of the group, which also raises funds for nonprofit organizations that also support their cause.

While many stars were in attendance, such as Jennifer Lopez and Rita Ora, who both performed, Beyoncé was certainly a highlight, and the crowd was stunned when her husband, Jay-Z, made a surprise appearance onstage and joined her to sing their 2003 hit song, “Crazy in Love.”

The couple certainly looked that way, as the usually private pair showed public displays of affection onstage. Jay-Z kissed Beyoncé at one point and held her around her waist. They looked like a couple newly in love, though they have been together for more than 10 years and have a daughter, Blue Ivy.

While rumors circulated that Blue Ivy may have a brother or sister soon, Beyoncé seemingly laid those rumors to rest once and for all. Onstage, the diva wore a form-fitting black leather leotard with mesh designs that showed off her defined waist and trim legs.

Other highlights at the Sound of Change concert included Madonna, 54, who told the crowd while onstage, “We cannot change this world nor begin to treat each other with human dignity without an education. Let tonight be the beginning of this revolution, because education is not a luxury; it is a basic human right. I invite you all to join my revolution of love. Join me tonight. The revolution of love starts here.”

Lopez also made sure to address the crowd and speak about the benefits of Chime for Change. “I believe my girls out there deserve the best education. They deserve the best in health. And I believe in justice for my girls everywhere.”
