Taylor Swift showed her support to former collaborator, Sadie Sink, with a surprise appearance in London.

On Thursday, May 7, the 36-year-old pop superstar made a striking appearance at the Harold Pinter Theatre to support Sink’s West End debut in Romeo & Juliet opposite Noah Jupe. She was accompanied by her fiancé, Travis Kelce.

In a video making the rounds on social media, Swift and Kelce were seen giving the Stranger Things star, 24, a standing ovation at the end of her performance.

Inside Sadie Sink and Taylor Swift’s bond

The 14-time Grammy winner and Sink previously collaborated on All Too Well: The Short Film, which was released in 2021.

The Dear Zoe actress starred alongside Dylan O'Brien in the short film, which was inspired by Swift’s 10-minute version of the breakup anthem.

Previously gushing over the Opalite hitmaker during an interview with Bustle, Sink  said , “She’s been such a huge part of my life.”

She added, “If a song of hers reminded me of a character, I would use it to get into a role. She had always been a little voice in my head, so it was super surreal…It was amazing that she recognized that in me somehow, that I would understand the song, the message, the story she was trying to tell.”

Before attending Sink’s performance, Swift and Kelce were also spotted leaving Gymkhana, an Indian restaurant, alongside British cinematographer Rina Yang, who has worked with the singer on several projects, including All Too Well: The Short Film.
