'Bridgerton' writers came up with Madame Delacroix's name because they were drinking 'cases and cases' of LaCroix every day

• A "Bridgerton" writer said Madame Delacroix's name resulted from her team's LaCroix consumption.
• On Thursday, she said the writers brainstormed French-sounding monikers for the on-screen modiste.
• When someone pitched Delacroix "as a joke" since they drank "so much LaCroix," she said it stuck.

Jess Brownell, a writer for Netflix's Regency drama "Bridgerton," said fans of Madame Genevieve Delacroix have the sparkling water brand LaCroix to thank for the modiste's sophisticated name.

As a guest host on Thursday's episode of "Bridgerton: The Official Podcast," Brownell said the show writers spitballed potential names for the dressmaker (Kathryn Drysdale), a working-class woman that pretends to be French to secure high-end clientele.

Eventually, she said their voracious LaCroix-drinking habit gave them an idea.

"When we were trying to come up with a French name, someone pitched as a joke Delacroix, and it stuck," Brownell told Gabrielle Collins, a producer Shondaland tapped to host the podcast.

Collins responded that she felt "gullible" for believing the story, leading Brownell to assure the host that she was telling the truth.

"I'm not lying. It's a joke at this point that TV's writer's rooms are obsessed with LaCroix. They're always stocked with it," she explained.

Brownell said the writing staff would "go through cases and cases" of the canned beverage each day they worked together.

"That's how she got her name," she added.

LaCroix, like Delacroix, isn't actually French

The town's chi-chi dressmaker rattles off a fake French accent for the majority of season one despite being an English commoner.

According to Drysdale, her character fakes her origin because members of Regency England's high society were only interested in Parisian modistes.

"She's putting on this act in order to maintain this lifestyle, in order to keep the clientele," she told People.

The actress continued, "It was really important for dressmakers to be from Paris [in order] to get the best clientele. You had to be French. And so those who weren't French would pretend to be French. They weren't necessarily Madames at all, but it was just part of the act."

The decision to name Delacroix after the popular beverage is ironic because LaCroix, like Delacroix, isn't French at all.

In fact, the carbonated water brand started in a family-owned brewery in La Crosse, Wisconsin, in 1981.

As Insider's Megan Willett-Wei reported in 2016, LaCroix's website said that the "'La' was taken from the city of La Crosse, and 'Croix' hails from the beautiful St. Croix River which flows between Wisconsin and Minnesota."

It also says that LaCroix is pronounced "La-CROY" and "rhymes with 'enjoy.'"

Many people, however, still call the beverage "La-KWAH," as it would be pronounced in the French language and in Delacroix's name.

Delacroix doesn't appear in Julia Quinn's books

"Bridgerton," which is executive produced by Shonda Rhimes, is an adaptation of Julia Quinn's best-selling romance novels. Major characters like the Bridgerton siblings, the Duke of Hastings, and the Featherington clan are all from the author's pages.

However, certain characters from the show, such as Delacroix and Will Mondrich, are unique to the Netflix original series.

"I wanted the show, the adaptation to be about more than just the Bridgertons, so I introduced new characters," "Bridgerton" showrunner Chris Van Dusen told Decider following the show's December 25 premiere.

He added, "For me, it was about expanding and really making the show about a world. It is about an entire society."
