A girl who became an internet star when a photo of her went viral has sold the meme as a non-fungible token (NFT).

Back in 2013, Chloe and her sister were filmed by their mum as she told them they were going to Disneyland.

The video has been watched more than 20 million times, and Chloe's hilarious reaction became a popular meme.

The image was bought by 3F Music, a Dubai-based music production company for 25 Ethereum - a type of cryptocurrency - that is worth around £54,000.

Chloe's mum, Katie, said: "We're so grateful for what it sold for,"

"The money is awesome but it's just the fact that we get to do this as a family is so much fun."

"We'll definitely get a Walt Disney holiday out of this next year!" she said.

NFTs of internet memes have sold for millions of dollars this year.

In February an NFT of Nyan Cat, was sold by the image's creator for 300 Ethereum, worth more than $880,000.

Non-fungible tokens, or NFTs, are a type of cryptographic asset. That means it is a thing - the asset - that is guaranteed by cryptography - meaning mathematical codes that can't be broken. It might sound quite complicated, but it isn't as complex as it first seems!

Let's break it down: You've probably heard of the term 'Bitcoin' before. Bitcoins are a type of cryptocurrency, which is a digital currency, like money, that can be used to buy and sell goods and services.

Similarly, NFTs are entirely digital, but there's a big difference between these and other cryptocurrencies you may have heard of.

Cryptocurrencies are 'fungible', which simply means a person is able to trade a currency like a Bitcoin for another completely identical Bitcoin. The two Bitcoins are 100 percent equal in value.

However, NFTs are described as 'non-fungible', which means they can't be replaced with or exchanged for another identical NFT as each token is entirely unique, similar to a rare trading card.

You can think about about in exactly the same way we look at famous paintings like the Mona Lisa - despite there being lots of copies, only one original painting exists. An NFT is like a digital certificate of authenticity which can be used to prove a person owns the original piece of digital artwork.

Just like posters of the Mona Lisa and the original painting, there's quite a big difference in price too.
