Anna Wintour has told Stephen Colbert's conservative character on Comedy Central's The Colbert Report to stop resisting gay marriage.

The 62-year-old, British-born Wintour has helmed fashion glossy Vogue since 1988.

She stopped by the show to pitch a Costume Institute exhibit currently on display at the Metropolitan Museum of Art.

When Wintour told Colbert that he could take a few more risks with his clothing now that he is endorsing gay marriage, Colbert said he wasn't endorsing but resisting the institution.

“You're in the fashion world, okay. Are there gay people in the fashion world?” Colbert asked. “Are you as angry about this gay marriage thing as I am?”

“I am thrilled,” she said, referring to President Obama's Wednesday endorsement of gay nuptials. “There were tears in the office of Vogue today, and the support of gay marriage. We're thrilled about the president.”

“You're reinforcing a hateful stereotype I hope you realize that,” Colbert responded.

“I think it's a long overdue endorsement and we're honored that he's come forward finally,” Wintour said. (Watch the complete segment at Colbert Nation.)
