Pop star Ariana Grande brought her "Wicked" co-star Cynthia Erivo on stage during her "Eternal Sunshine" tour stop in London over the weekend. The duo performed "For Good" from the upcoming "Wicked: For Good" film, as well as a rendition of Barbra Streisand's "Get Happy/Happy Days Are Here Again."

The performance took place at London's O2 Arena and was captured by fans on social media. Throughout their duet, Grande and Erivo exchanged smiles, and at one point, Grande kissed Erivo's hand. Attendees expressed admiration for their vocal blend and apparent chemistry.

Grande, who plays Glinda in the "Wicked" film adaptations, and Erivo, who portrays Elphaba, have maintained a close bond since filming the musical. Erivo previously described their connection on "The Drew Barrymore Show," noting that they often communicate through physical touch, such as holding hands, when words are insufficient.

Grande echoed these sentiments in an interview on Amy Poehler's "Good Hang" podcast, explaining that she "channel[s] a lot of energy through [her] hands" and that she and Erivo have worked to preserve their relationship despite busy schedules. She added that they "take care of each other so we can honor the project as much as humanly possible."

Erivo has previously addressed rumors about her relationship with Grande. In February, she told The Stylist that speculation about them being secret lovers or faking their friendship for the cameras was a "strange fascination." She also told Variety in May that she and Grande text daily and that any doubt about their friendship stemmed from people not knowing her well, stating, "If I’m a friend, then I’m a friend. If I’m not, then I’m not."

Fans reacted positively to the onstage collaboration, with many commenting on how well their voices complemented each other. The performance served to further highlight the camaraderie between the two actresses as they prepare for the release of "Wicked: For Good."
