Two of the most influential women in entertainment and fashion teamed up to throw a party in New York City.

TV talk show crowd Oprah Winfrey and Vogue editor-in-chief Anna Wintour, and Gap creative director Patrick Robinson co-chaired the annual Metropolitan Museum of Art’s Costume Institute Gala Benefit on Monday night (local time) in New York.

Justin Timberlake, Taylor Swift, Sarah Jessica Parker and Jennifer Lopez were there. Many were escorted by the designer who dressed them.

Winfrey walked the influx line with Oscar de la Renta, wearing a navy couture gown by the fashion designer.

She said she looked onward to going into the party and having a few shots of tequila.

When asked what goes on inside the Met Gala, Anna Wintour reacted with a laugh, Oh; we’re very, very well behaved.

Lady Gaga was slated to do at the ball but didn’t walk the red carpet. Instead, the well-known face with the most unusual dress was singer Katy Perry. She wore a dress that factually lit up with LED lights.
