It’s the kind of headline that makes you do a double-take. You’re scrolling through a feed and see a claim about a literal A-lister smelling like a seafood market. It sounds like a cheap tabloid hit piece, doesn’t it? Usually, it is. But every once in a while, there’s a grain of medical truth buried under the gossip.
The internet loves to gossip about celebrities who smell like fish. It’s a specific, weirdly persistent niche of celebrity rumors. Sometimes it’s just mean-spirited fan fiction. Other times, it's a conversation about a legitimate, rare metabolic disorder called Trimethylaminuria, or TMAU.
Honestly, the way we talk about body odor in Hollywood is pretty brutal. We expect these people to be airbrushed, scented with five-hundred-dollar oud, and fundamentally non-human. When a rumor starts that someone doesn't meet that standard, it spreads like wildfire.
The Science of TMAU: Why "Fish Odor Syndrome" is Real
Before we name names or look at the rumors, we have to talk about the biology. It’s not about hygiene. It’s not about not showering.
Trimethylaminuria is a condition where the body can't break down a specific compound called trimethylamine. This compound is produced in the gut when we digest certain foods—think eggs, liver, legumes, and various types of fish. Most people have an enzyme (FMO3) that turns that smelly stuff into something odorless. If that enzyme is missing or broken? That trimethylamine leaks out through sweat, breath, and urine.
It smells like rotting fish.
It’s rare. It’s isolating. And for a celebrity who spends their life under hot studio lights and high-definition cameras, it would be an absolute nightmare to manage.

The Most Famous Case: Camille Grammer’s Candid Reveal
If you want a real example of celebrities who smell like fish being discussed openly, you have to look at Camille Grammer. The Real Housewives of Beverly Hills alum didn’t just let rumors swirl; she addressed a very specific medical situation.
During her time on the show, there was a massive blow-up involving a "comment" made about her smelling like a certain sea creature. It was treated as the ultimate insult. But Grammer later clarified that she was dealing with significant health issues at the time, including Irritable Bowel Syndrome (IBS) and other complications that can affect how the body processes toxins.
It was a rare moment where the "stinky celebrity" trope met actual medical reality. It showed that what fans see as a "gross" quirk is often a grueling health battle.
Why Rumors Target Specific Stars Like Megan Fox or Rihanna
Then you have the rumors that seem to come from nowhere.
Take Megan Fox. For years, trolls have circulated stories about her personal hygiene, often using the "fishy" descriptor. Why? Usually, it’s based on a single out-of-context interview where she mentioned being messy at home or forgetting to flush the toilet. The internet takes a "messy house" comment and transforms it into a "body odor" rumor because that's how the celebrity gossip machine functions. There is zero evidence Fox has TMAU or any chronic odor issue.
Rihanna is another weird one. If you search for celebrities who smell like fish, her name occasionally pops up in weird corners of the web, which is hilarious because almost every peer who meets her—from Lil Nas X to Jennifer Lawrence—claims she smells like "heaven" or "marshmallows."

This happens because of "search intent manipulation." People search for a negative trait + a famous name just to see if anything exists. When enough people search for it, the suggestion starts appearing in Google’s auto-complete, creating a false narrative out of thin air.
Dealing with the Diet: The TMAU Celebrity "Protocol"
If a celebrity actually did have TMAU, their life would be a logistical puzzle. Doctors like those at the National Human Genome Research Institute point out that the only real "fix" is a brutal diet.
Imagine being a movie star and having to avoid:
- Seafood (obviously)
- Red meat
- Egg yolks
- Beans and peas
- Certain dark green vegetables like broccoli
It’s basically the opposite of the high-protein diets most actors use to get "superhero shredded." If a celeb was seen avoiding these foods religiously while also using acidic soaps (which help neutralize the smell on the skin), it might tip off a very observant fan.
But let’s be real. Most of the time, when we hear about celebrities who smell like fish, it’s just a stylist or an ex-assistant with an axe to grind. The power of a "smell rumor" is that it’s impossible to disprove through a screen. You can see someone's outfit is great. You can't smell them through Instagram.
The Intersection of IBS and Body Odor
It’s not just TMAU. Gut health is a massive topic in the "lifestyle" space right now. Small Intestinal Bacterial Overgrowth (SIBO) and severe IBS can lead to various types of body odor that don't respond to deodorant.

Celebrities are humans. They get sick. They have digestive flares.
The difference is that when you have a bad gut day, you stay home. When a celebrity has a bad gut day, they might have to sit in a chair for six hours of hair and makeup, then stand under 100-degree stage lights. Sweat happens. Chemistry happens.
Moving Past the Tabloid Gimmick
We need to stop using "smells like fish" as a punchline. For people actually living with Trimethylaminuria, it’s a debilitating condition that causes deep depression and social anxiety. When we turn it into a way to mock celebrities we don't like, we're essentially mocking a medical disability.
There’s a lot of nuance here. Some odors are caused by medications. Some are caused by the "keto breath" that comes with extreme weight loss for roles. Some are just... human nature.
Actionable Insights for Managing Body Odor Concerns
If you’ve landed here because you’re worried about your own scent—or if you’re just fascinated by the biology—here is how the pros (and the doctors) actually handle these issues:
- Test, Don't Guess: If you suspect you have more than just "gym sweat" issues, ask a GP about a urine test for trimethylamine levels. It's the only way to confirm TMAU.
- Check Your PH: Standard soaps are alkaline. TMAU odors are neutralized by acidic environments. Switching to a low-PH body wash (around 5.5) can make a massive difference for various skin-born odors.
- The Riboflavin Factor: Some studies suggest that high doses of Vitamin B2 (Riboflavin) can help boost the activity of the FMO3 enzyme in some people.
- Review Your Supplements: Choline and Carnitine supplements—common in pre-workout drinks—are major triggers for the fishy byproduct. If you're smelling "off," check your gym bag first.
The world of celebrities who smell like fish is mostly a mix of hyperactive fan theories and a few misunderstood medical realities. Next time you see a viral tweet about a star's scent, remember: it's probably just bad lighting, a vengeful ex-assistant, or a human being dealing with a very human body.
