A rainy Met Gala included a Rihanna pregnancy announcement, a tuxedoed choir and a trend true to the menswear theme: Emma Chamberlain, Zendaya, Teyana Taylor and many other women in pinstripes and other traditional men’s detailing.

The pop star seemed to confirm rumors she was pregnant when she met shouts of congratulations with: “Thank you!”

The superstar, embracing the night's celebration of dandyism, used the Met Gala steps as her official announcement of baby No. 3.
