Jill Biden, Jessica Chastain and Nick Jonas Toast Team USA in Paris

Just after 10 p.m. on Saturday, on the first weekend of the Paris Olympics, U.S. first lady Jill Biden walked through the wood doors of Ralph’s Restaurant Paris, past a towering display of red, white and blue flowers, and picked up two glasses of Champagne from a silver tray.

Ralph Lauren, the brand that owns the restaurant in the city’s Sixth Arrondissement and is a longtime outfitter of the U.S. Olympic and Paralympic teams, hosted the party to celebrate the U.S. team.

The bash — along with the Games — was a chance for the brand to show off its Olympic collections. The marketing potential of the Olympics is “as if you have three Super Bowls a day for 17 days,” said David Lauren, the brand’s chief innovation and branding officer.

With President Joe Biden sporting his U.S. Olympic merch back in the United States, the first lady was busy in France. Days earlier, she met with French President Emmanuel Macron, greeted the U.S. team at the U.S. Embassy in Paris and sat through the rain of the opening ceremony.

Surrounded by a large security detail, Biden surveyed the space and located her grandchildren — including Naomi Biden, who wore Ralph Lauren to her White House wedding with Peter Neal — who had congregated in a dimly lit backroom. She slid into a leather booth, where she remained for over an hour, away from prying eyes.

The event drew nearly 200 people, and felt a little like an unofficial embassy for the high-profile Americans in Paris for the Games. The crowd included actress Jessica Chastain, musician Nick Jonas, media personality Emma Chamberlain, comedian John Mulaney and snowboarder Shaun White. They drank martinis and snacked on a raw bar that filled an entire dining room.

Savannah Guthrie, a “Today” show co-host, said she thought the Olympics brought Americans together.

“We get to root for Team USA with everyone on the same side,” Guthrie said. “That feels good right now.”

Partygoers spent the evening sharing stories from their first rainy days in Paris.

In the restaurant’s courtyard, which featured a fountain and rustic benches decorated with blue and white cushions, David Lauren told Naomi Biden that he and his wife, Lauren Bush Lauren, had walked back to the hotel in ponchos, humming “Singin’ in the Rain.”

“We were laughing and dancing,” he said.

Naomi Biden said she watched the opening ceremony on television at a party thrown by LVMH, a partner of the Games, but empathized with those caught outside.

“I felt so bad for my Nana,” she said, adding that Celine Dion’s performance was a highlight for her. “She is just incredible.”

Guthrie and Hoda Kotb, her “Today” co-host, discussed which celebrities looked best despite the conditions.

“I think Tom Cruise looked amazing soaking wet with no umbrella,” Kotb said. “Elon Musk and Mick Jagger were also outside drenched.”

Their conversation was interrupted by Brian Roberts, chair and CEO of Comcast Corp., which owns NBC, who congratulated the duo on their ratings thus far: “Did you see the numbers? You guys are killing it.”

Jonas, who was standing with friends who work for Ralph Lauren, said he was heading straight from the party to see beach volleyball, on courts set against the Eiffel Tower.

“I always watched the Olympics growing up, but I’ve never been,” he said. “I’m very excited.”

David Lauren, who has met many of the American athletes through fittings, said he was excited to discover this year’s breakout stars.

“Some of these athletes are very famous, but some are from small towns and no one knows them,” he said.

“By the time they leave, they are going to be big stars. They are going to be on a Wheaties box. They are going to have a gold medal. They are going to be at the White House.”

He reflected on the meaning of the Games: “How many moments can you think of today when the whole world comes together with this kind of positive energy?”

A little after 11 p.m., the crowd started to disperse, and only about 50 guests remained, including the first lady and her grandchildren.

One guest remarked on the way out, “I can’t believe I am leaving a party before Jill Biden.”
