Ariana Grande and Cynthia Erivo Reunite at O2 London, Performing "For Good" for Sold-Out Crowd

For Good has been permanently marked on both Grande's and Erivo's palms with a tattoo, underscoring the duo's lifelong Wicked-era connection.
Erivo's London show look included an embellished Erdem bra-and-panties worn over a white blouse, paired with a white trench coat and black kinky boots, as styled by Jason Bolden.
The O2 London reunion marked Grande and Erivo’s first public live duet since Wicked: One Wonderful Night in November 2024, reconnecting through their Wicked history amid ongoing film work.
Grande has signaled she will take a step back from public life after completing the Eternal Sunshine Tour to prioritize health and well-being, a move covered as part of the surrounding discourse around the London performance.
Ariana Grande shocked a sold-out crowd at London's O2 Arena on Sunday when she brought out Wicked co-star Cynthia Erivo for a live duet. The two performed "For Good" — the emotional farewell song from the Wicked soundtrack — in what became an instant highlight of Grande's Eternal Sunshine Tour, according to Yahoo News.
The reunion marked the pair's first public live duet since their Wicked: One Wonderful Night NBC special in November 2024. Before "For Good," they also performed a mashup of "Get Happy" and "Happy Days Are Here Again," drawing rapturous cheers from the audience, Head Topics reported.
Grande wore a white dress for the surprise appearance. Erivo matched the moment in a white tuxedo-inspired look — an embellished Erdem bra-and-panties set over a white blouse, paired with a white trench coat and black boots, styled by Jason Bolden. The coordinated outfits made the cameo feel planned and polished, not thrown together last minute, Female First noted.
The crowd at the O2 Arena — one of the world's largest indoor venues, holding over 20,000 people — went wild. Both women were visibly moved during "For Good." Perth Now reported they were "so enthused they could sing" through their emotions. Short clips of the performance spread rapidly across social media within minutes.
The bond between Grande and Erivo goes deeper than a stage moment. Both women have permanently tattooed "For Good" on their palms as a tribute to their Wicked partnership. The tattoos signal that this friendship — and this song — means something lasting to both of them, Music News reported.
The Wicked film, released in late 2024, became a major cultural event. Grande played Glinda and Erivo played Elphaba. Their chemistry on screen translated directly to the O2 stage, where the two locked eyes and sang to each other just as their characters had done in the movie.
The London show is part of Grande's ongoing Eternal Sunshine Tour, which she is nearing the end of. The tour has been a major undertaking, and Grande has publicly said she plans to step back from public life once it wraps. She cited a need to focus on her health and personal well-being, Yahoo News reported.
That context made the London reunion feel even more significant. Fans see the Erivo duet as one of the tour's defining moments — a rare, high-profile guest appearance from a genuine friend and artistic equal, rather than a promotional stunt.
"For Good" is not a casual song choice. In Wicked, it is the goodbye between Glinda and Elphaba — two friends who changed each other forever. Hearing Grande and Erivo sing it live, in character as themselves this time, hit audiences on multiple levels at once, according to Head Topics.
The "Get Happy" and "Happy Days Are Here Again" mashup added a joyful contrast. That pairing — first made famous by Judy Garland and Barbra Streisand in 1963 — carries its own legacy. Grande and Erivo invoking it placed them in a long line of iconic female duos. Coverage from multiple outlets called it one of the standout live music moments of 2025.
