Katy Perry fit right in at the Victoria's Secret fashion show, donning two daring looks on the runway Wednesday in NYC. The first, a yellow, strapless bustier dress covered in pink hearts (which she completed with thigh-high boots). The second (also by designer Todd Thomas): A low-cut purple bustier that featured a big bustle. The newlywed, 26, sang a medley of her hits -- "Teenage Dream," ''Hot N Cold" and "California Gurls" -- as models, Adriana Lima, Chanel Iman and Karolina Kurkova, rocked the runway. In the audience: Debbie Harry, Serena Williams, Adrian Grenier, Nicky and Paris Hilton and Tyson Beckford. The show was missing some notable angels: Doutzen Kroes and Miranda Kerr, both of whom are pregnant. Heidi Klum, who hung up her angel wings earlier this year, also didn't walk. But it was a return for Adriana Lima, who opened the show in a giant set of wings -- her first major catwalk appearance since welcoming daughter Valentina last year. (US Weekly)
