Bill Nighy denies Anna Wintour romance after Met Gala — their pals beg to differ

He’s deNighying the romance rumors.

Bill Nighy set the record straight on his and Anna Wintour’s Met Gala debut as a couple, saying in a statement that he and the Vogue editor-in-chief have a platonic relationship.

“Bill and Anna have simply been great friends for two decades,” the “Love Actually” star’s rep told Page Six Monday.

“They are not in a relationship.”

The duo arrived together at Wintour’s big night and walked the red carpet arm-in-arm, prompting viewers to speculate that the fashionable fund-raiser was their big debut.

Both Nighy and Wintour had attended previous Met Galas solo.

The Post even heard that Wintour’s closest friends were “thrilled for them to be making it official at the Met.”

Apparently, they were only firming up their friendship — depending on whom you believe.

The alleged non-couple sparked romance rumors in 2018 when they were spotted taking in two plays together, but even then the “Best Exotic Marigold Hotel” actor shut down any hearsay.

The new couple, who are both Brits, also set tongues wagging last December when they were spotted together at a New York screening of Nighy’s Oscar-nominated film, “Living.”

But the friendship appeared to take a romantic turn three years ago when they dined together, and eyewitnesses told The Post that Wintour, 73, was “beaming” the whole night.

“She looked happy and in very good company. She was beautifully made-up and she was smiling so much — she had her sunglasses off the entire time!” the source said of the 2020 sighting.

“They were sitting together in a corner enjoying a frothy coffee.”

Wintour’s decision to debut her alleged relationship with Nighy at the Met Gala was rumored to hold special meaning for the magazine maven, who has chaired or co-chaired the famed fashion event since 1995.

This year’s Met Gala theme, “Karl Lagerfeld: A Line of Beauty,” honored the late German fashion designer who was the creative director of Chanel until his death in 2019.

Nighy, 73, split from his long-term love, actress Diana Quick, in 2008. They have one daughter, Mary Nighy.

Wintour was married to David Shaffer from 1984 to 1999. The former couple have 35-year-old daughter Bee and 37-year-old son Charlie.

She then married Shelby Bryan in 2004 but divorced in 2020.
