'Heavenly' Met Gala in New York brings out the stars

Rihanna and Katy Perry were among the celebrities who took the theme of the Met Gala very religiously this year.

Rihanna looked absolutely papal when she arrived in a Maison Margiela pearl- and crystal-embellished gown by John Galliano, complete with a matching papal mitre and necklace.

Perry also wowed in a metallic mini-dress, long boots and massive feathery wings. She looked like a post-punk angel. Her wingspan was so broad she was forced to turn sideways as she entered the museum.

This year's theme is the influence of Catholicism on fashion.

Both singers have been to the gala before. Last year, Rihanna was dressed in Commes des Garcons, with stagey pink on her cheeks. Perry wore a veiled dress created just for her by John Galliano.

The gala is a fundraising benefit for the Metropolitan Museum of Art in New York City.

It always includes big names from Hollywood, fashion, music and art worlds.

Take a look at some of the styles from the invitation-only event.
