The 19-year-old pop star shared that she has synesthesia, a neurological condition where the stimulation of a sense like hearing triggers the brain to think of unrelated things like shapes or colors. In Rodrigo's case, hearing songs instantly makes her sense a color. In a video for Vogue shot as she got ready for her first Met Gala, Rodrigo said that she has "minor, baby synesthesia." "So when I listen to songs I'll like, see colors," she said. "Many songs on SOUR are purple, like 'driver's license' is purple. But 'good 4 u' is like a purpley-blue, 'jealousy, jealousy' is like bright red. 'déjà vu' is like orange and pink and light purple. It's like, lighter and more pastel-y." Rodrigo, who donned a light purple Versace gown with matching purple opera gloves and butterfly clips for her Met Gala debut, said that she likes "having purple as the cohesive color throughout my whole SOUR era."

"We actually haven't had a purple moment yet, and it's her favorite color, so it just felt right," Chloe said of Rodrigo's Met Gala look, joking: "We were saving it." The teen star is midway through her American tour in support of her Grammy-winning debut album, and added some fun fashion elements along the way. During a stop in Detroit in April, she asked fans to wear "prom attire." "Since it's prom seasonnnn I thought maybe we could turn SOUR TOUR into SOUR PROM????" she asked. "Would u guys be down? prom attire?"

Wade, which guaranteed the right to abortion. "Because we're in D.C., I couldn't pass up the opportunity to say how heartbroken I am over the Supreme Court's potential decision," Rodrigo said Wednesday night, to cheers from the crowd. "Our bodies should never be in the hands of politicians," she continued. "I hope we can raise our voices to protect our right to have a safe abortion, which is a right that so many people before us have worked so hard to get. It's so important." Rodrigo also signed on to Planned Parenthood's Bans Off Our Bodies petition, alongside more than 150 other young artists and creators, to call for reproductive rights. In a full-page ad in The New York Times published on Friday, Rodrigo and stars like Ariana Grande, Hailey Bieber, Kendall Jenner and many more denounced the decision to overturn Roe.
