Celebrities Who Became Famous After a Viral Moment

Fame used to move through record labels, studios, casting directors, magazines, and television.

Now, one clip can change everything.

A bedroom cover, a TikTok dance, a meme song, a funny reaction, a Walmart performance, or a random photo can turn an unknown person into a public figure almost overnight. But viral fame is not the same as lasting fame. Some people disappear after the moment. Others turn the attention into music careers, acting roles, brand deals, tours, businesses, or long-term online followings.

Here are celebrities who became famous after a viral moment.

Justin Bieber

Justin Bieber’s rise is one of the original internet-to-superstar stories.

Before he was selling out arenas, Bieber was a Canadian teenager whose mother uploaded videos of him singing covers to YouTube. Those clips caught the attention of talent manager Scooter Braun, who helped connect him with the music industry.

Lil Nas X

Lil Nas X turned internet fluency into a music-industry breakthrough.

His song “Old Town Road” first spread through memes before exploding on TikTok.

Charli D’Amelio

Charli D’Amelio became one of TikTok’s first true breakout stars.

Her rise came through short dance videos at a time when TikTok was still defining its celebrity class.

Mason Ramsey

Mason Ramsey became famous in one of the most unexpected places possible: Walmart.

In 2018, a video of Ramsey yodeling Hank Williams’ “Lovesick Blues” in a Walmart store went viral.

Rebecca Black

Rebecca Black became famous through one of the most discussed viral videos of the early YouTube era.

Her song “Friday” was uploaded in 2011 and quickly became a viral hit, though much of the attention was harsh and mocking.

Bhad Bhabie

Bhad Bhabie’s fame began with a talk-show clip that became a meme.

Danielle Bregoli appeared on Dr. Phil in 2016, and her “Cash me outside” phrase spread rapidly online. The clip turned her into a viral figure before she transformed the attention into a rap career under the name Bhad Bhabie.

Shawn Mendes

Shawn Mendes built his first major audience through Vine.

Before his hit songs and arena tours, Mendes posted short cover clips on the six-second video platform.

Doja Cat

Doja Cat was making music before “Mooo!,” but that viral cow-themed video changed her visibility.

She later became one of pop and rap’s most unpredictable stars with songs like “Say So,” “Kiss Me More,” “Woman,” and “Paint the Town Red.”

Addison Rae

Addison Rae became famous through TikTok dance videos before moving into music, acting, and fashion.

She joined TikTok in 2019 and quickly became one of the platform’s biggest creators.

Bella Poarch

Bella Poarch became famous through one of TikTok’s most recognizable lip-sync videos.

Her “M to the B” clip, built around facial expressions and precise head movements, became one of the platform’s biggest viral videos.

Khaby Lame

Khaby Lame became one of the biggest social media stars in the world without saying a word.

His videos mocked overly complicated “life hack” clips by silently showing the obvious solution, then giving the camera his signature deadpan gesture.

Brittany Broski

Brittany Broski became famous as “Kombucha Girl.”

A video of her tasting kombucha for the first time went viral because her face moved through confusion, disgust, reconsideration, and approval in just a few seconds. The clip became a reaction meme that spread far beyond its original context.

Sophia Grace and Rosie

Sophia Grace Brownlee and Rosie McClelland became famous after a viral YouTube cover.

Their performance of Nicki Minaj’s “Super Bass” became popular online and led to regular appearances on The Ellen DeGeneres Show.

Salt Bae

Nusret Gökçe became globally known as Salt Bae because of one dramatic seasoning video.

The Turkish chef and restaurateur went viral in 2017 after a clip showed him slicing meat and sprinkling salt down his forearm in an exaggerated, stylish motion.

Susan Boyle

Susan Boyle became famous after a television audition went viral around the world.

Her 2009 Britain’s Got Talent performance of “I Dreamed a Dream” shocked audiences who had underestimated her before she sang. The audition spread rapidly online and became one of the defining viral talent-show moments of the late 2000s.

Psy

Psy was already famous in South Korea before “Gangnam Style,” but the music video turned him into a global name.

The 2012 video became a worldwide internet event because of its horse-riding dance, visual humor, and endlessly repeatable chorus. It crossed language barriers and became one of the first YouTube videos to reach truly historic global numbers.

Lil Tay

Lil Tay became famous through controversial viral videos as a child internet personality.

Her clips showed a young girl performing an exaggerated rich-and-rude persona, flashing money, cars, and attitude. The videos spread quickly because they were strange, uncomfortable, and hard to ignore.

Emma Chamberlain

Emma Chamberlain became famous through YouTube videos that felt different from the polished influencer style of the time.

Her editing, humor, awkwardness, and casual honesty made her feel more like a real person than a carefully managed online personality. While she did not rise from one single meme in the same way as “Kombucha Girl” or “Alex From Target,” her early videos created repeated viral momentum.
