TikTok: How do Charli and Dixie D'Amelio deal with online bullying?

The sisters have faced cyberbullying on the social media app TikTok

The D'Amelio sisters have been speaking out about online bullying - including on TikTok.

Charli and Dixie have become huge names on the video platform - which has an age restriction of 13.

Charli D'Amelio has more than 88 million followers and is the most followed star on the app while her older sister Dixie has a fan base of 38.8 million. But along with their newfound fame, they've also faced cyberbullying.

"A lot of people around my age, some younger, some older, are the prime ages for most types of bullying," said Charli in a recent interview with Seventeen magazine.

"We all need to be more conscious of the things we say about people because it can really affect them…. As a society, we definitely need to be more careful with our words and make sure we are treating people with kindness."

Dixie has also criticised people who she said "bullied" UK singer Taio Cruz off TikTok.

Charli has been very vocal about people who criticise the way others look and she hopes to help fans dealing with issues around body image.

Dixie has also faced bullying online, and she's come up with her own way of dealing with some of the hateful things people say.

"I have all my comments off so I don't really get mean ones," said the 19-year-old.

"But I usually just make a joke out of it or ignore it, because it doesn't matter. They don't know who you are as a person so it's not worth my time to argue with someone or defend myself."

Taio Cruz quits TikTok

Taio Cruz was only on TikTok for a matter of days before deleting his account.

Other people on Tiktok have also complained that they've had negative messages on the app, including singer Taio Cruz who has announced he is quitting TikTok "for good" - just a week after joining.

The musician, whose hits include Dynamite and Break Your Heart, said he had been targeted by "hateful" videos and comments.

"My intention was to make some fun videos and interact with my fans, but some, whom I won't mention, were averse to that.

"For my own mental health, I would rather be where I'm welcomed, for now, TikTok is not that place. Social media shouldn't be like this, sadly it is."

Dixie D'Amelio spoke up in his defence saying: "This makes me so sad... Y'all bullied a legit music artist off TikTok in under a week… WHAT??? Just be nice."

TikTok says it is investigating what happened.
