Today is a great day for lash Reporter: Even making his debut at the met gala last week but this morning he's waking up to a different reality losing nearly 3 million of his 16.5 million subscribers since Friday when he was publicly attacked by a mentor who helped launch his career.

Reporter: In a video that's been viewed more thank 36 million times, fellow beauty vlogger tati Westbrook not only claim Charles betrayed her by advertising for one of her competitors, but alleges that on a number of occasions he has harassed some straight men.

Demi low separate to and SHAWN Mendes unfollowing the star and thousands of his followers posts videos online throwing out their makeup. Setting it on fire. Websites recording the loss of hundreds of thousands of followers in realtime. Even this apology video from Charles didn't help quiet the fury. I owe everybody an explanation. I have been involved in a lot of very unique and strange situations that have left people confused or upset and I learned the hard way about, um, ways that I can interact with boys that I'm interested in and also ones that I should or shouldn't be talking to. That video disliked more than 2.5 million times. This mass reaction of pulling support for celebrities after scandal known as cancel culture. It's like nothing we've ever seen before in the YouTube community. There's been nobody that has lost that quickly over basically one video. And Charles has been silenced since posting that apology Westbrook posting a cryptic message saying in part we can hold truth and inspire change without grabbing on to hate. Celebrating pain will only bring it to your door. Those are wise words and I also would just say this kid's 19 years old. I mean I don't know all the details but I certainly feel bad that he's going through something so public right now and so I tried to talk about that with my daughters. He came on "Strahan & Sara" and my kids love him and my girls came in to see him. He's 19. He's a kid. It's very overwhelming and to see this is a little disheartening. He did seem affected by it.
