Trending: Toddler becomes internet sensation after video of her swearing while doing the ice bucket challenge goes viral

A toddler has become an unlikely internet sensation after taking part in the Ice Bucket Challenge before promptly blurting out the F-word – much to the horror of her grandmother.

Three-year-old Scarlett-Rose Davis begged her grandparents to let her take part in the craze which is currently taking the world by storm in aid of motor neurone disease.

But grandmother Carla Davis-Ball, said she ‘could have died’ when the little girl blurted out ‘f***ing hell’ after tipping an icy bucket of water over her head – and the episode was all caught on camera.

Mrs Davis-Ball recorded the footage of Scarlett-Rose being doused with warm water from a cooking pot after nominating a young friend called Marshall to take the challenge last weekend.

After she put it on Facebook and her husband Stuart Ball, 33, uploaded it to YouTube, it has been viewed more than 40,000 times since Monday, and has been shared several thousand times around the world.

The 40-year-old, from Coalpool in Walsall, West Midlands, said: ‘I couldn’t believe it when she came out with that language.

‘She has picked up a few bad words when we have gone out for meals or into town.

‘It did shock me but she’s so clever I’m not surprised she’s picked it up. We told her it was a naughty word.

‘Children have brains like sponges and I can’t stop it. But she does know it’s wrong.

‘I have to say when I heard her swearing I nearly died with laughter. I know it’s wrong but it’s the same reaction most adults would have after being drenched in ice water.

‘We did tell her not to say rude words and she is normally very good and polite.’
