Lorde sends fans wild as Sadie Sink crashes concert

Lorde sent her fans into a frenzy by bringing out Sadie Sink during her London show over the weekend.

On the heels of wrapping up the North American leg of her 2025 Ultrasound world tour in support of her fourth album, Virgin, the Royals hitmaker kicked off the UK and European leg of Sunday, November 17, at London’s O2 Arena.

As fans were vibing during the New Zealand singer’s show, she doubled the fun by inviting the Stranger Things star onstage.

Lorde, whose real name is Ella Marija Lani Yelich-O'Connor, and Sink’s latest gig features Melodrama track Green Light.

The two jumped up and down with the sea of fans while performing on the stage.

Although the concertgoers truly had an experience of a lifetime, fans online quickly rallied to social media to share their excitement over the unexpected collaboration, with one saying, "Let that Sink in."

Another wrote on X (formerly Twitter), "A surprise appearance that's actually surprising for once," followed by a third, "Two icons, one stage, zero warning."

A fourth gushed, "OMG, that's such a cool collab!! [star eyes emoji] I saw a clip of the dance break, Sadie's vibes are so good with the song."

"Sadie walking out during Green Light? That's cinematic energy right there only Lorde could turn a London show into a full crossover episode," a fifth wrote.

Notably, Sink, recently starred in Tony-nominated Broadway play John Proctor Is the Villain, which features Green Light, making the onstage moment more meaningful and special.
