The video of babies in nappies performing skating stunts to a hip-hop beat has been watched 3.8 million times on YouTube alone in the past week.
In the clip daredevil "roller-babies" leap over fences and railings as well as each other in a city park.
After pressing play on a giant ghetto blaster that is bigger than them, they execute all manner of flips and somersaults.
The troupe of 96 special-effects roller-babies groove to a remix of the Sugarhill Gang's Rapper's Delight.
The 60-second film was shot at London's Pinewood Studios as part of mineral water brand Evian's Live Young international television and web video campaign.
The advert is proving a huge hit online with YouTube viewers alone watching the US version almost 1.8 million times.
The international version has been seen over 1.5 million times and the French clip over 500,000 times.
The Evian babies were last screened 11 years ago performing an underwater ballet.
Evian's worldwide director of brand Michael Aidan said that the firm was trying to sell drinkers a "dream".
He said: "In the majority of countries in recent years, our communication has been very fact-based.
"But consumers expect more from a big brand – emotion, dream. This is what we want to achieve – hence this breakaway and back to roots campaign."
One female YouTube viewer said of the ad: "It's one of the cutest things I've ever seen".
The ad was first shown on TV in France, Belgium and Canada over the weekend.
An Evian spokesman said that no date has been set yet for showing the ad on TV in the UK.
He said: "It's working so well virally that plans for TV in the UK are still under review."

Registering 5,081,441 views in the past week alone, an international advertisement featuring roller-skating babies has become a YouTube sensation. French and US versions of the advert for Evian mineral water have also seen 500,000 and 1.5 million visitor hits respectively.

"It's one of the cutest things I've ever seen," said one YouTube viewer. Reviewer Saul Relative says, "You'll find yourself watching this feel good video commercial again and again."

The babies roller-skate to a remix of The Sugarhill Gang's top 40 hip hop single Rapper's Delight.

Euro RSCG began the web video campaign on Friday, July 3.  The advertisement has been aired on television in France, Belgium, and Canada.  "It's working so well virally that plans for TV in the UK are still under review," said an Evian representative.
