September 19, 2026. Los Angeles. George Lucas finally opened his museum, and Katy Perry turned the opening-night gala at the Lucas Museum of Narrative Art into a date night with Justin Trudeau. Forty-one, jet-black hair parted down the middle, and a white velvet gown cut close to every curve.

The Look: White Velvet, Christian Siriano
A strapless white crushed-velvet column from Christian Siriano’s spring 2027 collection, shown at New York Fashion Week just over a week earlier. A sculptural draped neckline, a corseted bodice, ruching at the hip and a slim skirt to the floor. Silver open-toe sandals and a delicate diamond bracelet. Nothing else needed.
Next to Trudeau in a black suit and an open-collar white shirt, it was the cleanest look of the night: one color, one line, a lot of Katy.

Why It Mattered
It was only the couple’s second official red carpet. They made their debut in June 2026 at the Tribeca Festival premiere of her concert film The Lifetimes Tour – Live from Paris, a little under a year after they were first linked in July 2025, and they confirmed the relationship on Instagram that December. On the gala carpet they held hands, traded looks and laughed through the photos.
The guest list was huge: Kim Kardashian, Lewis Hamilton, Oprah Winfrey, Michael B. Jordan, Greta Gerwig, Laura Dern, Pharrell Williams. The museum, founded by Lucas and Mellody Hobson in Exposition Park, opened to the public on September 22.

None of that is a nude scene, and Katy Perry has never done one. For her sexiest official moments, start with the California Gurls cotton-candy cloud and the Teenage Dream bed and pool scenes. Everything ranked lives on the Katy Perry hub, and more of her archive sits on Katy Perry on Scandal Planet.
