Pippa Middleton has set up her own company, it emerged today, although exactly what it will do remains unknown.
The Duchess of Cambridge's sister registered a company called PXM Enterprises Ltd with Companies House on May 24, appointing herself as sole director.
According to Companies House documents, the 29-year-old is the sole shareholder in the business, whose address is given as 19 Portland Place in London.
Miss Middleton, who was propelled into the spotlight as a bridesmaid at her sister's wedding to the Duke of Cambridge, joined her parents' party company after leaving university.
She has published her own guide to entertaining, called Celebrate, last year, but it was widely panned.
She has also now writes a column for Waitrose's monthly magazine.
But it remains unclear what her new business will be.
The building at 19 Portland Place is leased by OJK Ltd, which provides accountancy services to clients in the music, sports and broadcast media industries, but the company today would not confirm whether Miss Middleton is a client.
In her first column in Waitrose Kitchen's April edition, the 29-year-old offered an insight into her experiences of student life at the University of Edinburgh, where she apparently spent afternoons making sushi in front of the rugby.
In her first magazine piece - entitled Pippa's Friday Night Feasts - she described "pre-Monday melancholy" and "feeling exhausted" on Friday evenings, suggesting she is now familiar with the trials and tribulations of the working week.
