Cardi B is calling out the gap between what people say and what they actually mean.
The Grammy-winning artist signed on as the face of "Real Talk Interpreter," Zevia's newest and biggest campaign to date.
It marks Cardi B's first creative partnership with the better-for-you soda brand, and it puts her plainspoken reputation directly behind Zevia's concept.
The pitch in question? Zero sugar, real ingredients, and no filler.
"Zevia keeps it real with the ingredients, and I’ve never been one to bite my tongue," Cardi B said in a press release.
"With ‘Real Talk Interpreter,’ we’re bringing that same energy to everyday moments and saying what everyone is really thinking."

The timing tracks with where the category is headed.
The zero-sugar beverage market is on pace to grow from roughly $6.3 billion in 2026 to $14.5 billion by 2033.
Zevia is using Cardi B's bluntness to stand out inside the competitive soda aisle.
"Her authenticity, humor and confidence help us introduce Zevia to new audiences and show that great-tasting, zero sugar soda made with real ingredients can still have plenty of personality and flavor," Zevia CMO Kirsten Suarez shared.
The campaign runs across national streaming TV, video, social media, and retail.
The Filters Are Coming Off
Cardi B's role as the "Real Talk Interpreter" is centered on translating everyday small talk into what people think deep down.
Two hero spots carry the concept. "Potluck" is set inside the kind of neighborly chat that hides real opinions.
Meanwhile, "Guidance Counselor" is where polite parent-teacher language gets hilariously decoded in real time.
Cardi B sips Zevia Orange Creamsicle in one spot and Creamy Root Beer in the other, cutting through the small talk with her usual bluntness.
The rollout doesn't stop at just these two spots.
Later this week, Cardi B will ask fans on Instagram and TikTok to submit their own filtered snapshots.
She's after dating-app screenshots, group-chat drama, and anything left unsaid.
Selected entries will then be pulled onto Zevia's and Cardi B's channels, creating interactive, engaging user-generated content.

Additionally, a companion Zevia x Cardi B Real Summer Sweepstakes offers weekly prizes.
A grand-prize bundle of autographed merchandise and free products is also in the mix.
This approach fits a strategy that beverage brands keep returning to, where celebrity marketing is used more as a built-in content pipeline.
Cardi B brings a Grammy win and 161 million Instagram followers to the deal, so any brand she signs starts with instant reach.
She's no rookie to this game plan either, recently fronting Fashionphile's 2026 global ambassador push built on her handbag-collecting habit.
Before that, she also led Yahoo Mail's Planner campaign, using her packed schedule to explain daily inbox anxiety.
Cardi B's directness was already hers before Zevia ever called.
Brands now hunt for talent whose personal branding already fits the product, so the endorsement clicks the second the camera rolls.
The Real Cost of Sounding Like Everyone Else
Zero-sugar soda is mainstream now, and its growth is why brand personality beats a plain ingredient claim.
A 2023 Nielsen analysis found that celebrity-endorsed products saw a 29% lift in purchase intent among shoppers aged 18 to 34.
This number is the case for casting Cardi B.
Her unfiltered reputation hands Zevia a personality no spokesperson-free rival can match, while the fan submissions keep the content engine running.

Three takeaways stand out for marketers watching this category:
- Lead with personality when claims run dry: Once every competitor can say "zero sugar, real ingredients," a recognizable face becomes the thing shoppers remember.
- Build recurring content into the deal: Fan-submission formats stretch one talent contract into weeks of fresh material.
- Match the persona to the product truth: The right star already embodies what the brand claims, so the endorsement carries built-in credibility.
A category rewards the brand that gets remembered between purchases, and a well-matched personality does more of this memory work than product claims could.
Our Take: Can Bluntness Sell Soda?
Liquid Death got here first, using an irreverent brand voice to stand out.
Zevia is now chasing the same space, and we think that what it got right is the casting.
Cardi B's identity is saying what everyone else edits out, and Zevia's pitch is no fake sweeteners and no vague marketing.
Put these two together, and the endorsement reads like a mission statement.
The campaign works as long as the submissions stay raw and Cardi B keeps improvising off-script.
The second it gets polished into something safe, the whole thing falls apart.
