Celebrity allergies you didn’t know about

Ariana Grande—Tomatoes? Yep, Tomatoes.

In 2019, Ariana Grande had to cancel shows after a surprise allergic reaction left her struggling to breathe. Turns out, tomatoes were the unexpected culprit.

She described the feeling as “swallowing a cactus,” and said her throat nearly closed. Since then, tomatoes are off the menu—and fans got a reminder that allergies can hit out of nowhere.

Bethenny Frankel—A Fish Allergy That Turned Dangerous

In 2018, Bethenny Frankel had a life-threatening reaction after unknowingly eating soup with fish. She lost consciousness for 15 minutes and was rushed to the ER and ICU.

She now carries an EpiPen everywhere and urges others to do the same. Later allergy testing revealed more triggers—fish, shellfish, nuts, wheat, dairy, and more—with fish being the most severe.

Emmy Rossum—Gluten Isn’t Just a Trend for Her

While judging Top Chef in 2014, Emmy Rossum casually revealed she has mild celiac disease. It’s a serious form of gluten intolerance that triggers an immune response in the body.

She’s been gluten-free for over 15 years, sharing that it causes painful canker sores. As Emmy put it herself, “Everyone reacts to allergens differently”—and hers definitely pack a punch.

Chrissy Teigen—Altitude + Allergies = Trouble

While in Utah for a wedding in 2019, Chrissy Teigen experienced extreme lip swelling from an allergic reaction. The culprit? Altitude sickness triggering angioedema—a condition she had no idea could be set off that way.

She shared a selfie with her swollen lips, joking, “Goodbye world.” Leave it to Chrissy to turn even a scary allergy moment into a learning (and slightly hilarious) one.

Kelly Clarkson—Allergies So Bad, She Joked About Living in a Bubble

For someone with powerhouse vocals, Kelly Clarkson has a surprisingly long allergy list. In 2013, she tweeted about being allergic to peanuts—among other things—and wasn’t thrilled about it.

She joked, “I’m officially going to live in a bubble. Look out Flaming Lips, I’m stealing your idea!” Humor aside, serious food allergies like hers require extra caution—especially on tour.

Demi Lovato—Adorable, But Allergic

Demi Lovato may love animals, but her immune system doesn’t. She’s allergic to cats and dogs—especially cats, which can set her off from 10 feet away.

She once joked she can sense a cat in the room before seeing it. Pet lovers beware: Demi might adore your furry friend… from a safe distance.

Eva Longoria—Sneeze-Free Scents Only, Please

Strong perfumes might smell nice to some—but for Eva Longoria, they were a major problem. Even a whiff of someone else’s fragrance could leave her sneezing nonstop.

In 2009, she decided to take matters into her own hands and created a hypoallergenic scent. Proof that when fashion meets function, even allergies can inspire a business move.

Miley Cyrus—No Gluten, No Dairy, No Filter

Food allergies aren’t always obvious—and for Miley, they sparked a lot of wrong assumptions. Back in 2012, she clapped back at body-shamers and set the record straight.

“For everyone calling me anorexic I have a gluten and lactose allergy,” she tweeted. “It’s not about weight it’s about health. Gluten is crapppp anyway!” Classic Miley—real, raw, and not holding back.

Zooey Deschanel—When Allergies Kill the Vibe

Zooey Deschanel once called herself “the worst person to eat with”—and she wasn’t kidding. After a blood test revealed allergies to eggs, dairy, and wheat, dining out became a major hassle.

She tried going full gluten-free vegan, but it didn’t stick. As she told Vulture, “At a certain point, you just have to go, ‘This gets in the way of my living too much.’”

Sabrina Carpenter—An Apple a Day? Nope.

Turns out, Sabrina Carpenter is not here for doctor-approved snacks. In 2016, she confirmed she’s allergic to apples after a fan joked about sending her a bunch.

Her response? “But I’m allergic.” So yeah—an apple a day might keep the doctor away, but for Sabrina, it’s sending her straight back to the allergist.

SZA—Allergic to… Basically Everything

For SZA, eating isn’t just a lifestyle—it’s a challenge. She’s allergic to a laundry list of foods, including berries, beans, beef, dairy, eggs, shellfish, mushrooms, olives, and more.

In a 2018 interview, she joked, “I have all these f*cking food allergies that are consuming my soul.” Safe to say, her menu is probably the smallest thing about her.

Debra Messing—Nature Was Not Her Friend

Growing up in Rhode Island surrounded by grass and pollen, Debra Messing was constantly sick without knowing why. Doctors misdiagnosed her symptoms for years, blaming everything from strep to bronchitis.

Eventually, an allergist gave her the real answer—she was one of the most allergic patients he’d seen in 14 years. Debra finally understood the cause of her sneezing, swelling, and “Kermit the Frog” voice—and got the relief she needed.

David Beckham—Breathing Through the Pressure

You’d never guess it watching him on the field, but David Beckham has had asthma since childhood. That didn’t stop him from dominating international soccer and making history in four countries.

He managed his condition quietly while becoming one of the sport’s top global icons. Proof that even with asthma, greatness doesn’t take a back seat.

Sarah Hyland—A Ruff Start to Filming

While shooting the Modern Family pilot, Sarah Hyland had an unexpected run-in with her manager’s dog. One lick later, she broke out in intense hives all over her leg.

“It looked like smallpox,” she said, describing the reaction as so bad it looked burned. Safe to say, dogs may be cute—but Sarah’s immune system says absolutely not.

Busy Philipps—Sinus Struggles and Smart Solutions

Busy Philipps has dealt with severe sinus issues since childhood, often feeling intense facial pain and pressure. Even during her Dawson’s Creek days, she was quietly battling blocked sinuses nearly 100% of the time.

Multiple surgeries helped, but her allergies still lingered—so she turned to a low-histamine diet. Now she avoids high-trigger foods like spinach, citrus, and nightshades, keeping her meals simple and her symptoms in check.

Jessica Alba—Beauty Products Gone Wrong

Haircare is usually part of the glam, but for Jessica Alba, it turned into a nightmare. After using common styling products, she ended up in the ER with swollen, infected corneas.

Her vision was blurred for nearly a week, and doctors suspected several ingredients were to blame. “It was scary,” she shared—reminding us that even beauty routines can come with serious risks.

After 17 years together, Jessica Alba and Cash Warren call it quits—here’s what led to their surprising split.

Gabrielle Union—When Smoke Isn’t Just Annoying

For Gabrielle Union, cigarette smoke isn’t just unpleasant—it’s a real health issue. She’s allergic to it, which reportedly led to tension behind the scenes at America’s Got Talent.

When co-host Simon Cowell allegedly smoked indoors on set, she raised the issue with the fire marshal. It wasn’t just about comfort—it was about protecting her well-being.

Simon Cowell gave Carrie Underwood one piece of advice on Idol—and it changed everything.
