The event featured performances from U.K. artist Jessica Winter and DJ Venus X to kick off the "I'm not a blonde, I'm a Bleach" campaign. Pattinson and Waterhouse were first romantically linked in July 2018, when a source told PEOPLE they were "dating" after they were spotted putting on some PDA while out together in London. The pair began living together in London during the COVID-19 pandemic, where he filmed his titular superhero role in The Batman. An insider told PEOPLE that their relationship appeared to be "on the fast track" at the time. "They are very loved-up," the source said in July 2020. "They haven't been together that long. But everything seems on the fast track. They are always laughing and smiling at each other."

"I'm pretty sure she's not normally into watching superhero movies," Pattinson said. "And just seeing that it was capturing her attention the entire time, and then she held my hand and touched it [to her face] and I could feel a little tear. And I was like, 'No way!'"
