Someone has shared one of Shane's old vids from his Shane and Friends web series and titled it: 'I think Shane Dawson is a pedophile. Here's my proof.'
In the video, Shane makes a bunch of offensive pedophilia jokes, including calling an infant a "sexy child".
The video has since been deleted but clips and extracts have been circulating on Twitter and people are furious.
After noticing the online backlash, Shane made an apology vid where he denied the pedophila allegations and said sorry for making inappropriate jokes.
"[I want to] go on record saying I am not a f***ing pedophile. Got it? Great. There's my statement," he said.
"I loved the feeling of making somebody shocked and laugh because they couldn't believe what was coming out of my mouth, I wasn't confident enough to make smarter jokes."
He has also tweeted a lengthy apology in response to a fan.
"The jokes are old and were out of context. i’ve been molested in my childhood," he tweeted.
"I dealt with it by making jokes. and i’ve grown up and stopped doing that. People just don’t want to let me move on. This whole experience was insane and awful and I don’t wish it on anyone."
