Princess Eugenie has a Sex and the City moment while Beatrice parties with Dave

All Princess Eugenie needed was a pair of Manolo Blahniks and her Sex and the City experience would have been complete. Attending a party at a trendy SoHo tea house in New York, the British royal had a definite Carrie Bradshaw moment as she rubbed shoulders with the New York style set.

With her hair cut into a trendy layered bob, and wearing a chic monochrome outfit, Eugenie looked in her element at a Fabergé luncheon at upmarket French tea salon Ladureé.

Eugenie looked in her element as she rubbed shoulders with stylist Mary Fellowes at a party in New York's trendy SoHo district.

She was snapped chatting away to celebrity stylist Mary Fellowes, who has dressed the likes of Liv Tyler, Paris Hilton, Adele, Amy Adams and Claire Danes, and was the former fashion director for the Turkish edition of Vogue.

Eugenie has become a must-have on the guest list for the Big Apple's society parties. This week's bash took place in one of New York's newest venues – only having opened on Tuesday.

Ladureé – the well-known Champs Elysees tea room which is famous for its macaroons - have finally found a home in NYC. They already have successful tea rooms in London, Dublin, Switzerland, Luxembourg, Sweden, Italy and Japan.

Eugenie has fully emersed herself in new York life since starting work for online auction house Paddle8.

Meanwhile over 3,500 miles away, her sister Beatrice stepped out with boyfriend Dave in London.

She moved Stateside last summer, with the idea of staying for a three-month placement. But the granddaughter of the Queen landed a permanent role at Christmas after impressing her bosses.

As much as she is relishing life Stateside, she is no doubt missing her friends and family though, not least her sister, Princess Beatrice.

While Eugenie lunched in New York, Beatrice was also socialising back in London – attending an exclusive jewellery party with her boyfriend Dave Clarke.

The pair joined fellow guests at the Mayfair launch of fine jewellery designer Sabine Ghanem's new Harlequin collection.
