This is Zoe Sugg, aka Zoella. She is arguably one of the most marketable people in Britain right now.
She is held in the same esteem as pop stars and actors by her young fans, who hang on her every word.
Her hair and make-up tutorials are a phenomenon.
The success of her videos led to her signing a publishing deal with Penguin – her first novel, Girl Online, is out in November and there is a follow-up planned for next year – and scoring major presenting gigs.
The 24-year-old and a number of her fellow YouTubers were recently signed up by the BBC to guest-host a Sunday Radio 1 show.
While the presenting opportunities excite her, creating videos in the comfort of her own home remains the priority. "I still love my little home on YouTube, really," she admitted.
"I think it’s like a little safe place and also a lot of people are still loving that as opposed to traditional media, so it’s fun trying [TV/radio] out and doing it but I wouldn’t say it’s something that I 100% want to go into right now.
"I wouldn’t say I wouldn’t want to do that ever, but I never had any goals in mind like, ‘Oh, I think I’ll carry this on because I’d love to be a presenter.'"
Inevitably for someone who became a teen idol through lifestyle coaching, brands are tripping over themselves to be associated with her.
The adverts are being shown online, on TV, and across public transport in London.
She said she's turned down a large number of opportunities to avoid "self-combusting".
"I keep it as real and as me as possible," she said.
