The biggest stars in fashion aren't just the designers showcasing their work at New York, London, Paris and Milan.

No, they're the celebrity children taking front row at fashion week. And the leader of the pack? David and Victoria Beckham's four-year-old daughter Harper Seven.

The youngest of their four children has been making headlines with her chic clothes and causing sales in her outfits to skyrocket within hours of a photograph appearing online. There's even a Harper Beckham fashion blog dedicated to the little one's style credentials.

And while many might think it's the work of her mother and fashion extraordinaire Victoria, it appears that's not the case.

“Goodness, a full-time blog just on her, does she really?” Victoria told The New York Times this week. “That’s quite amazing. I had no idea. And perhaps a little odd.”

“I suppose it says a lot about the world we are living in today,” she continued. 

“And yet it doesn’t surprise me. Harper is incredibly chic — especially this morning in that coat from Christopher [Bailey from Burberry], and wears some incredibly sweet things.

“She’s a very stylish little thing with her own sense of how she wants to dress. She tends to choose exactly what she wears herself.”

But Victoria says her favourite item of clothing might come as a surprise to the fashion pack. 

“More than anything,” she said, “she loves her football jersey.”
