N*E*R*D's Pharrell Williams has been partying with Oprah Winfrey.
Winfrey -- who hosted the Costume Institute Gala benefit earlier this week -- made a splash at the event's official after party, joining Williams for part of N*E*R*D's performance.
Earlier in the night Winfrey had promised to leave her good behavior at home, revealing, "I like tequila... My hair is down for the party." Her BFF Gayle King supported her statement, "She loves a tequila shot, I’ll tell you that."
Winfrey and Williams weren't the only stars in attendance, with Katy Perry, Anna Wintour, Diddy and Usher also spotted.
N*E*R*D -- who were only enlisted to perform three songs - showcased their new track "Hot N Fun", before Shay Haley lef the stage, making way for a special guest appearance by Diddy who helped Williams keep the party going.
That's what we call a party in the U.S.A.
