YouTube sensation James Charles has seen his popularity plummet after a public falling-out with fellow social media influencer, Tati Westbrook.

The 19-year-old make-up artist lost over three million followers since Ms Westbrook uploaded a video to YouTube criticising the star last week.

He currently has just over 13.5 million YouTube subscribers.

And he was estimated to be worth over £9m before the Ms Westbrook’s video went viral.

Mr Charles was the first male face of CoverGirl.

And has worked with A-listers like Kim Kardashian and Kylie Jenner.

Since the video went viral, famous followers of Mr Charles have also unfollowed him on social media, including Ms Kardashian and Ms Jenner.

Tati Westbrook, another YouTube make-up artist, criticised Mr Charles for manipulating others’ sexuality in the video.

Ms Westbrook accused him of attempting to convince straight men he was interested in that they were gay.

She also condemned Mr Charles for talking crassly about sex in front of her friends and family.

Since the allegations came to light, singer Zara Larsson has claimed Mr Charles attempted to seduce her boyfriend despite knowing he’s straight.

Tati Westbrook has previously worked closely with Mr Charles and promoted him on her YouTube channel.
