Meryl Streep Just Revealed She's Family with Anna Wintour

File this under delightful Hollywood curveballs: Meryl Streep and Anna Wintour aren’t just linked by a certain cerulean sweater — they’re actually related. And yes, Meryl is just as amused as you are.

Yep, Meryl and Anna are actually related

On the Thursday, April 30 episode of Jenna Bush Hager’s podcast 'Open Book,' 76-year-old Meryl Streep — currently stealing scenes on 'Only Murders in the Building' — reacted to the discovery that she and former Vogue editor-in-chief Anna Wintour are family. When Bush Hager, 44, floated the rumor, Streep cut in with the correction: sixth cousins.

Streep traced it back to Bucks County, Pennsylvania, on her mother ’s side — the Wilkinsons — and called the whole thing pretty funny. Earlier this month, 'Today' spotlighted the genealogy via Ancestry.com, which says Streep and Wintour share fifth great-grandparents, Thomas Smith and Elizabeth Kinsey. That shared pair is what makes them sixth cousins.

• The connection: Streep and Wintour are sixth cousins.
• Shared ancestors: fifth great-grandparents Thomas Smith and Elizabeth Kinsey.
• Family roots Streep cited: Bucks County, Pennsylvania; English lineage through her mom’s Wilkinson line.
• Reactions: Streep’s 'Devil Wears Prada' co-stars Anne Hathaway, Stanley Tucci, and Emily Blunt were stunned. Blunt, 43, blurted, "No, you’re not. That’s fantastic."

No, Miranda Priestly wasn’t an Anna impression

When the film dropped in 2006, plenty of people assumed Streep’s ice-cold Runway editor Miranda Priestly was a straight-up Anna Wintour clone. Streep says that was never the plan. She didn’t know Wintour back then, and the only bosses she’d had were men, so she borrowed from their leadership styles instead of Anna’s. As she got to know Wintour later, she came to the conclusion that Anna’s, well, kind of great — and at 76, she’s overseeing content across the entire Conde Nast empire, from The New Yorker and Traveler to GQ and all the international Vogues.

"I didn’t want Miranda to be modeled on Anna."

Streep joked that if she’d known they were related, she might have copied Wintour after all — or, as she quipped, "Maybe she’s copying me."

A Vogue cover — with Wintour actually on it

Streep also explained how she got Wintour to pose alongside her on the cover of Vogue for the first time. According to Streep, Wintour asked if she wanted to do the cover; Streep, who loves saying no, declined — unless Wintour did it too. Wintour initially balked, but after a little back-and-forth, they decided to mess with the idea together. The shoot, Streep says, was fun, and Wintour was a good sport.

The Prada refresher — and what’s next

For anyone catching up: 'The Devil Wears Prada' (2006) is based on Lauren Weisberger’s 2003 novel, which pulled from her time as Wintour’s assistant at Vogue. Streep played Miranda Priestly, the imperious editor-in-chief of Runway. She’s stepping back into those heels for the sequel. 'The Devil Wears Prada 2' hits theaters on Friday, May 1.
