A family, who has grown increasingly famous on TikTok, have sadly been the targets of a vile arson attack.

After the attack, the Smithy Family shared a video of their house in South London, U.K, on TikTok, informing their 2.5 million followers of what had happened.

In the clip, their car has been visibly destroyed by the fire and their family home was blackened by the smoke from the inferno.

They also posted a video of the house while it was set alight before emergency services arrived on the scene.

Dad Nick said: "We all got out the house OK, the kids are fine... the dogs are OK. The house is not OK. The kids are in a safe place. To the people who have done this, you could have killed our family and not only our family, my neighbors, my friends. It's unforgivable."

This horrible crime comes after the family gained a lot of popularity over the last year - so much so, trolls even leaked their address online which sparked a series of events, including unwanted takeaways and even escorts sent to their home.

London Fire officials stated that it was the fire from the car that spread to the property and it could have caused serious harm if it wasn't dealt with immediately.

It took over twenty firefighters to extinguish the blaze. The cause of the fire is still being investigated, and the perpetrators have yet to be found.

An LFB spokesperson said: "We were called to reports of a car alight that had spread up the outside of the house.

"There were a number of mobility scooters parked outside which had caught alight and were producing a large amount of smoke and flames.

"Everyone was out of the building before we arrived, and crews worked incredibly hard to prevent further damage to the inside of the property and to neighboring properties."

Nick Smith and his wife Jess first gained popularity on the app after sharing videos with their kids Jack, Amelia, Isabella, and Teddy.

Their fame meant Nick could give up work as a builder and work full-time as a TikTok star. And their page isn't just filled with sweet family moments, either. They also help out charities and over Christmas, they collected around £60,000 ($80,000) worth of gifts for the Salvation Army - a charity that helps the homeless and families living in poverty.

Fans of the family have spoken out after the horrifying events...

"This family is truly amazing, such genuine, lovely people and they didn't deserve this... what a cruel, sadistic, vile thing to do... glad u find it funny that u just lit the bin... how would a life behind bars suit u... coz if u had killed anyone of those people that's where u would be... arson is NO joke...u really need help if u think this was funny... I'm so glad they all made it out okay... I'm so sorry this has happened to you all," one Facebook user wrote.

Another commented: "Why would anyone do this. There are some vile humans in this world. Can we even call them human? This was obviously intentional and in turn, it was a risk to human life. Family's children pets."

Our hearts go out to the Smithy family during this terrible time.
