Jim Dyson/Getty Images Just days after pictures emerged of Katy Perry packing on the PDA with Justin Trudeau, the singer had a very interesting response to a fan's proposal while performing in London. The "California Gurls" singer brought her Lifetimes Tour to The O2 arena on Monday, October 13, and was surprised by an eager fan named Darren, who proposed to her after being invited onstage. "I heard you're single," Darren said per footage posted on TikTok. "You heard I'm single? That's interesting," Perry, 40, responded. Darren then got down on one knee and unfurled a sign reading, "Katy Perry, will you marry me?" @charl_robbins a live proposal at @Katy Perry the lifetimes tour, london night 1. sorry darren, you're just the one who got away ❤️🩹 #katyperry #lifetimestour #lifetimestourlondon @The O2 ♬ original sound - charlotte As the audience broke into laughter, a shocked Perry said, "Are you kidding me? Not today!" "You know, you really should have asked me about 48 hours ago," she then quipped, letting Darren down gently. 'Private' Katy Perry and Justin Trudeau Are Still Seeing Each Other Perry asked the fan what he looked for in a partner. As he described looking for a "good lover," Perry walked away from Darren towards two other fans she invited onto the stage and joked, "Let's go far away from that man!" "I can't believe I brought you on stage. This is real freaky," she continued to jest. Addressing Darren, she added, "No, you can stay. There's nothing wrong with you. It's me. It's me." Perry's surprising moment came just two days after the Daily Mail published photos of the singer and Trudeau, 53, sharing a cozy moment aboard her Caravelle yacht off the coast of Santa Barbara, California.

The singer and the politician first sparked dating rumors in July after they were spotted together on two occasions on the same day. The pair were first seen enjoying a stroll with Perry's dog in Montreal's Mount Royal Park. Later that day, they were spotted dining at Montreal restaurant Le Violon, per footage obtained by TMZ in late July.

Us Weekly broke the news in June that Perry had split from longtime fiancé Orlando Bloom, with whom she shares daughter Daisy Dove, 5. (Trudeau, meanwhile, split from wife Sophie Grégoire Trudeau in 2023.) Sophie Trudeau Talks About Love as Justin and Katy Perry's Romance Heats Up "Katy and Orlando have split but are amicable," a source told Us at the time. "It's not contentious at the moment. Katy is of course upset but is relieved to not have to go through another divorce, as that was the worst time in her life." "Orlando and Katy have been shifting their relationship over the past many months to focus on coparenting," reps for the pair said in a joint statement in July. "They will continue to be seen together as a family, as their shared priority is - and always will be - raising their daughter with love, stability and mutual respect." Bloom, 48, addressed the breakup during a September appearance on Today to promote his latest film, The Cut. "I'm great, man. I'm so grateful. We have the most beautiful daughter," Bloom told Today host Craig Melvin. "You know, when you leave everything on the field, like I did in this movie, I feel grateful for all of it. And we're great. We're going to be great. It's nothing but love."
